Last modified Jun 16, 2026

CVE-2012-3509 is a vulnerability of currently unknown severity. Multiple integer overflows in the (1) _objalloc_alloc function in objalloc.c and (2) objalloc_alloc macro in include/objalloc.h in GNU libiberty, as used by binutils 2.22, allow remote attackers to cause a denial of service (crash) via vectors related to the "addition of CHUNK_HEADER_SIZE to the length," which triggers a heap-based buffer overflow.. EPSS estimates a 3.60% chance of exploitation in the next 30 days.
