stdlib 1.24.4 (golang) pkg:golang/stdlib@1.24.4 Affected range <1.24.13 Fixed version 1.24.13 EPSS Score 0.765% EPSS Percentile 51st percentile Description During session resumption in crypto/tls, if the underlying Config has its ClientCAs or RootCAs fields mutated between the initial handshake and the resumed handshake, the resumed handshake may succeed when it should have failed. This may happen when a user calls Config.Clone and mutates the returned Config, or uses Config.GetConfigForClient. This can cause a client to resume a session with a server that it would not have resumed with during the initial handshake, or cause a server to resume a session with a client that it would not have resumed with during the initial handshake. Affected range <1.25.11 Fixed version 1.25.11 EPSS Score 0.560% EPSS Percentile 42nd percentile Description Decoding a maliciously-crafted MIME header containing many invalid encoded-words can consume excessive CPU. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.768% EPSS Percentile 51st percentile Description Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.588% EPSS Percentile 44th percentile Description The Dial and LookupPort functions panic on Windows when provided with an input containing a NUL (0). Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.755% EPSS Percentile 51st percentile Description Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.781% EPSS Percentile 51st percentile Description When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.813% EPSS Percentile 53rd percentile Description When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C memory and a crash. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.621% EPSS Percentile 45th percentile Description If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.349% EPSS Percentile 27th percentile Description Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.615% EPSS Percentile 45th percentile Description During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls. Affected range <1.25.8 Fixed version 1.25.8 EPSS Score 0.728% EPSS Percentile 50th percentile Description url.Parse insufficiently validated the host/authority component and accepted some invalid URLs. Affected range <1.24.11 Fixed version 1.24.11 EPSS Score 0.459% EPSS Percentile 37th percentile Description Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption. Affected range <1.24.12 Fixed version 1.24.12 EPSS Score 1.945% EPSS Percentile 78th percentile Description The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.613% EPSS Percentile 45th percentile Description The ParseAddress function constructs domain-literal address components through repeated string concatenation. When parsing large domain-literal components, this can cause excessive CPU consumption. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.626% EPSS Percentile 46th percentile Description The processing time for parsing some invalid inputs scales non-linearly with respect to the size of the input. This affects programs which parse untrusted PEM inputs. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.361% EPSS Percentile 28th percentile Description Validating certificate chains which contain DSA public keys can cause programs to panic, due to a interface cast that assumes they implement the Equal method. This affects programs which validate arbitrary certificate chains. Affected range <1.24.9 Fixed version 1.24.9 EPSS Score 0.384% EPSS Percentile 30th percentile Description Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains. Affected range <1.25.11 Fixed version 1.25.11 EPSS Score 0.763% EPSS Percentile 51st percentile Description (*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically based on the number of SAN entries multiplied by the hostname's label count. Because x509.Verify validates hostnames before building the certificate chain, this overhead occurred even for untrusted certificates. Affected range <1.24.12 Fixed version 1.24.12 EPSS Score 0.643% EPSS Percentile 46th percentile Description archive/zip uses a super-linear file name indexing algorithm that is invoked the first time a file in an archive is opened. This can lead to a denial of service when consuming a maliciously constructed ZIP archive. Affected range <1.24.11 Fixed version 1.24.11 EPSS Score 0.274% EPSS Percentile 19th percentile Description An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in the leaf certificate. For example a constraint that excludes the subdomain test.example.com does not prevent a leaf certificate from claiming the SAN *.example.com. Affected range >=1.24.0 <1.24.6 Fixed version 1.24.6 EPSS Score 0.489% EPSS Percentile 38th percentile Description If the PATH environment variable contains paths which are executables (rather than just directories), passing certain strings to LookPath ("", ".", and ".."), can result in the binaries listed in the PATH being unexpectedly returned. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.292% EPSS Percentile 21st percentile Description On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.371% EPSS Percentile 29th percentile Description If a trusted template author were to write a <script> tag containing an empty 'type' attribute or a 'type' attribute with an ASCII whitespace, the execution of the template would incorrectly escape any data passed into the <script> block. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.314% EPSS Percentile 23rd percentile Description CVE-2026-27142 fixed a vulnerability in which URLs were not correctly escaped inside of a tag's attribute. If the URL content were to insert ASCII whitespaces around the '=' rune inside of the attribute, the escaper would fail to similarly escape it, leading to XSS. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.290% EPSS Percentile 21st percentile Description Context was not properly tracked across template branches for JS template literals, leading to possibly incorrect escaping of content when branches were used. Additionally template actions within JS template literals did not properly track the brace depth, leading to incorrect escaping being applied. These issues could cause actions within JS template literals to be incorrectly or improperly escaped, leading to XSS vulnerabilities. Affected range <1.25.8 Fixed version 1.25.8 EPSS Score 0.328% EPSS Percentile 25th percentile Description Actions which insert URLs into the content attribute of HTML meta tags are not escaped. This can allow XSS if the meta tag also has an http-equiv attribute with the value "refresh". A new GODEBUG setting has been added, htmlmetacontenturlescape, which can be used to disable escaping URLs in actions in the meta content attribute which follow "url=" by setting htmlmetacontenturlescape=0. Affected range <1.25.9 Fixed version 1.25.9 EPSS Score 0.290% EPSS Percentile 21st percentile Description tar.Reader can allocate an unbounded amount of memory when reading a maliciously-crafted archive containing a large number of sparse regions encoded in the "old GNU sparse map" format. Affected range <1.25.11 Fixed version 1.25.11 EPSS Score 0.370% EPSS Percentile 29th percentile Description When returning errors, functions in the net/textproto package would include its input as part of the error. This might allow an attacker to inject misleading content to errors that are printed or logged. Affected range <1.25.10 Fixed version 1.25.10 EPSS Score 0.390% EPSS Percentile 31st percentile Description ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function. For example, the query "a1=x&a2=x&...&a10000=x&hidden=y" can forward the parameter "hidden=y" while hiding it from the proxy's Rewrite function. Affected range <1.24.12 Fixed version 1.24.12 EPSS Score 0.276% EPSS Percentile 19th percentile Description During the TLS 1.3 handshake if multiple messages are sent in records that span encryption level boundaries (for instance the Client Hello and Encrypted Extensions messages), the subsequent messages may be processed before the encryption level changes. This can cause some minor information disclosure if a network-local attacker can inject messages during the handshake. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.526% EPSS Percentile 41st percentile Description The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a response is large, this can cause excessive CPU consumption. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.443% EPSS Percentile 35th percentile Description When Conn.Handshake fails during ALPN negotiation the error contains attacker controlled information (the ALPN protocols sent by the client) which is not escaped. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.534% EPSS Percentile 41st percentile Description Despite HTTP headers having a default limit of 1MB, the number of cookies that can be parsed does not have a limit. By sending a lot of very small cookies such as "a=;", an attacker can make an HTTP server allocate a large amount of structs, causing large memory consumption. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.526% EPSS Percentile 41st percentile Description Parsing a maliciously crafted DER payload could allocate large amounts of memory, causing memory exhaustion. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.443% EPSS Percentile 35th percentile Description The Parse function permits values other than IPv6 addresses to be included in square brackets within the host component of a URL. RFC 3986 permits IPv6 addresses to be included within the host component, enclosed within square brackets. For example: "http://[::1]/". IPv4 addresses and hostnames must not appear within square brackets. Parse did not enforce this requirement. Affected range <1.24.8 Fixed version 1.24.8 EPSS Score 0.419% EPSS Percentile 34th percentile Description tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A maliciously-crafted archive containing a large number of sparse regions can cause a Reader to read an unbounded amount of data from the archive into memory. When reading from a compressed source, a small compressed input can result in large allocations. Affected range <1.25.8 Fixed version 1.25.8 EPSS Score 0.201% EPSS Percentile 10th percentile Description On Unix platforms, when listing the contents of a directory using File.ReadDir or File.Readdir the returned FileInfo could reference a file outside of the Root in which the File was opened. The impact of this escape is limited to reading metadata provided by lstat from arbitrary locations on the filesystem without permitting reading or writing files outside the root.

golang.org/x/net 0.38.0 (golang) pkg:golang/golang.org/x/net@0.38.0 Affected range <0.55.0 Fixed version 0.55.0 EPSS Score 0.478% EPSS Percentile 38th percentile Description The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com". Affected range <0.53.0 Fixed version 0.53.0 EPSS Score 0.781% EPSS Percentile 51st percentile Description When processing HTTP/2 SETTINGS frames, transport will enter an infinite loop of writing CONTINUATION frames if it receives a SETTINGS_MAX_FRAME_SIZE with a value of 0. Uncontrolled Resource Consumption Affected range <0.55.0 Fixed version 0.55.0 CVSS Score 6.5 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H EPSS Score 0.248% EPSS Percentile 16th percentile Description In Go Net (golang.org/x/net) before verion 0.55.0, parsing arbitrary HTML can consume excessive CPU time, possibly leading to denial of service. Affected range <0.55.0 Fixed version 0.55.0 EPSS Score 0.188% EPSS Percentile 9th percentile Description Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering. Affected range <0.55.0 Fixed version 0.55.0 EPSS Score 0.178% EPSS Percentile 8th percentile Description Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering. Affected range <0.55.0 Fixed version 0.55.0 EPSS Score 0.178% EPSS Percentile 8th percentile Description Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering. Affected range <0.55.0 Fixed version 0.55.0 EPSS Score 0.178% EPSS Percentile 8th percentile Description Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree. This can be leveraged to execute XSS attacks in applications that attempt to sanitize input HTML before rendering. Affected range <0.45.0 Fixed version 0.45.0 EPSS Score 0.482% EPSS Percentile 38th percentile Description The html.Parse function in golang.org/x/net/html has an infinite parsing loop when processing certain inputs, which can lead to denial of service (DoS) if an attacker provides specially crafted HTML content. Affected range <0.45.0 Fixed version 0.45.0 EPSS Score 0.502% EPSS Percentile 39th percentile Description The html.Parse function in golang.org/x/net/html has quadratic parsing complexity when processing certain inputs, which can lead to denial of service (DoS) if an attacker provides specially crafted HTML content.

Details The smartLeftAngle() function in html/smartypants.go:367-376 performs an out-of-bounds slice operation when processing a < character that is not followed by a > character anywhere in the remaining text. https://github.com/gomarkdown/markdown/blob/37c66b85d6ab025ba67a73ba03b7f3ef55859cca/html/smartypants.go#L367-L376 If the length of the slice is lower than its capacity, this leads to an extra byte of data read. If the length equals the capacity, this leads to a panic. PoC package main import ( "bytes" "fmt" "github.com/gomarkdown/markdown/html" ) func main() { src := []byte("<a") fmt.Printf("Input: %q (len=%d, cap=%d)\n", src, len(src), cap(src)) var buf bytes.Buffer sp := html.NewSmartypantsRenderer(html.Smartypants) sp.Process(&buf, src) // panics: slice bounds out of range fmt.Printf("Output: %q\n", buf.String()) } Impact This vulnerability will lead to a Denial of Service / panic on the processing service. -- The Datadog Security Team OWASP Top Ten 2017 Category A9 - Using Components with Known Vulnerabilities Affected range >=0 Fixed version Not Fixed CVSS Score 7.5 CVSS Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H EPSS Score 1.042% EPSS Percentile 60th percentile Description The package github.com/gomarkdown/markdown is a Go library for parsing Markdown text and rendering as HTML. Prior to pseudoversion 0.0.0-20230922105210-14b16010c2ee, which corresponds with commit 14b16010c2ee7ff33a940a541d993bd043a88940, parsing malformed markdown input with parser that uses parser.Mmark extension could result in out-of-bounds read vulnerability. To exploit the vulnerability, parser needs to have parser.Mmark extension set. The panic occurs inside the citation.go file on the line 69 when the parser tries to access the element past its length. This can result in a denial of service. Commit 14b16010c2ee7ff33a940a541d993bd043a88940/pseudoversion 0.0.0-20230922105210-14b16010c2ee contains a patch for this issue.

golang.org/x/sys 0.31.0 (golang) pkg:golang/golang.org/x/sys@0.31.0 Affected range <0.44.0 Fixed version 0.44.0 EPSS Score 0.114% EPSS Percentile 2nd percentile Description NewNTUnicodeString does not check for string length overflow. When provided with a string that overflows the maximum size of a NTUnicodeString (a 16-bit number of bytes), it returns a truncated string rather than an error.
