An out-of-bounds memory access vulnerability exists in the libstdc++ parallel search implementation due to an undersized internal buffer. A local attacker can exploit this flaw by providing crafted search data to an application compiled with parallel mode, causing the process to crash and leading to a Denial of Service (DoS).\n\n## Affected\n\n- `gcc (all versions)`\n- `gcc-toolset-15-gcc (all versions)`\n- `gcc-toolset-16-gcc (all versions)`\n- `mingw-gcc (all versions)`\n- `compat-gcc-295`\n- `compat-gcc-296`\n- `compat-gcc-32`\n- `compat-gcc-34`\n- `gcc`\n- `compat-gcc-32`\n- `compat-gcc-34`\n- `compat-gcc-44`\n- `gcc`\n- `gcc (all versions)`\n- `gcc-toolset-14-gcc (all versions)`\n- `gcc-toolset-15-gcc (all versions)`\n- `mingw-gcc (all versions)`\n- `gcc (all versions)`\n- `gcc-toolset-14-gcc (all versions)`\n- `gcc-toolset-15-gcc (all versions)`\n- `gcc-toolset-16-gcc (all versions)`\n- `mingw-gcc (all versions)`\n- `gcc (all versions)`\n- `gcc13 (all versions)`\n- `openshift/ose-rhel-coreos-8 (all versions)`\n- `openshift/ose-rhel-coreos-9 (all versions)`\n- `openshift/ose-rhel-coreos-9 (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":34.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
