CVSS: 8.1EPSS: 4%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-2023-39322
08 Sep 2023 — QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in size. Las conexiones QUIC no establecen un límite superior en la cantidad de datos almacenados en el búfer al leer mensajes post-handshake, lo que permite que una conexión QUIC maliciosa provoque un crecimiento ilimitado de la memoria.

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 go.mod toolchain directive, introduced in Go 1.21, can be leveraged to execute scripts and binaries relative to the root of the module when the "go" command was executed within the module. This applies to modules downloaded using the "go" command from the module proxy, as well as modules downloaded directly using VCS software.

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.

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.

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.
