CVE-2023-29404

A flaw was found in golang. The go command may execute arbitrary code at build time when using cgo. This can occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This can be 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. This affects usage of both the gc and gccgo compilers.

Ameya Darshan and Jakob Ackermann discovered that Go did not properly validate the amount of memory and disk files ReadForm can consume. An attacker could possibly use this issue to cause a panic resulting in a denial of service.
