CVSS: 8.1EPSS: 0%CPEs: 5EXPL: 0CVE-2023-39323 – Arbitrary code execution during build via line directives in cmd/go
https://notcve.org/view.php?id=CVE-2023-39323
05 Oct 2023 — Line directives ("//line") can be used to bypass the restrictions on "//go:cgo_" directives, allowing blocked linker and compiler flags to be passed during compilation. This can result in unexpected execution of arbitrary code when running "go build". The line directive requires the absolute path of the file in which the directive lives, which makes exploiting this issue significantly more complex. Las directivas de línea ("//line") se pueden utilizar para evitar las restricciones de las directivas "//go:cg... • https://go.dev/cl/533215 •

https://notcve.org/view.php?id=CVE-2023-39319
08 Sep 2023 — The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack.

08 Sep 2023 — The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS attack.

https://notcve.org/view.php?id=CVE-2023-29409
02 Aug 2023 — Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web... • https://github.com/mateusz834/CVE-2023-29409 • CWE-400: Uncontrolled Resource Consumption •

11 Jul 2023 — The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value. A flaw was found in Golang, where it is vulnerable to HTTP header injection caused by improper content validation of the Host header by the HTTP/1 client. A remote attacker can inject arbitrary HTTP headers by persuading a victim to v... • https://github.com/LuizGustavoP/EP3_Redes • CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') CWE-436: Interpretation Conflict •

https://notcve.org/view.php?id=CVE-2023-29405
08 Jun 2023 — The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. Flags containing embedded spaces are mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in the argument of another flag. This only affects usage of the gccgo compiler. • https://go.dev/cl/501224 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •

08 Jun 2023 — The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. The arguments for a number of flags which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled through the LDFLAGS sanitization.

https://notcve.org/view.php?id=CVE-2023-29403
08 Jun 2023 — On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors closed, opening any files can result in unexpected content being read or written with elevated privileges. Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may ... • https://go.dev/cl/501223 • CWE-668: Exposure of Resource to Wrong Sphere •

08 Jun 2023 — The go command may generate unexpected code at build time when using cgo. This may result in unexpected behavior when running a go program which uses cgo. This may occur when running an untrusted module which contains directories with newline characters in their names. Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected). • https://go.dev/cl/501226 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
