CVE-2012-3509
5.0 · MEDIUMOverview
CVE-2012-3509 is a medium-severity vulnerability affecting gnu binutils. It was published on September 5, 2012 and has a CVSS 2.0 base score of 5.0 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 5.0, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from gnu. Update binutils to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
