{"id":"ALPINE-CVE-2026-97034","details":"When using GCC, building a malicious package that uses cgo could cause arbitrary command execution at link time via untrusted GCC spec files (\"specs\" or \"*.spec\"). When linking with \"-fopenmp\", \"-fopenacc\", or \"-fsanitize=\" in \"#cgo LDFLAGS\", GCC's built-in link spec evaluates \"%:include(libgomp.spec)\" or \"%:include(libsanitizer.spec)\" and searches for spec files in \"-L\" and sysroot directories (including subdirectories and multilib sibling directories such as \"../lib64\"), as well as the working directory when \"-fopenmp\" or \"-fopenacc\" is used or when \"-fsanitize=\" is combined with \"-static\" or \"-static-lib*\". The go command now rejects \"-L\", \"-isysroot\", and \"-Wl,-syslibroot\" directories (and the working and package directories when applicable) that contain GCC spec files, and disallows \"@\" and \"-\" prefixes in \"-fsanitize=\" compiler flag values.","modified":"2026-11-13T10:30:02.952373660Z","published":"2026-11-11T05:19:57.397Z","upstream":["CVE-2026-97034"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-97034"}],"affected":[{"package":{"name":"go","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/go?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.26.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-97034.json"}}],"schema_version":"1.9.2"}
