A flaw was found in binutils. A heap-buffer-overflow vulnerability exists when processing a specially crafted XCOFF (Extended Common Object File Format) object file during linking. A local attacker could trick a user into processing this malicious file, which could lead to arbitrary code execution, allowing the attacker to run unauthorized commands, or cause a denial of service, making the system unavailable.
AnalysisAI
Heap buffer overflow in GNU Binutils XCOFF linker allows arbitrary code execution when a local user processes a malicious object file. Red Hat Enterprise Linux versions 6 through 10 are confirmed affected via CPE data. …

Within 24 hours: Identify all RHEL 6-10 systems running GNU Binutils (rpm -qa binutils) and document which support AIX/PowerPC cross-compilation. Within 7 days: Restrict XCOFF file linking to trusted sources only; implement code review and digital signature validation for object files in build systems. …
