CVE-2012-2807: Multiple integer overflows in libxml2, as used in Google Chrome before 20.0.1132.43 and other products, on...

Security readout for executives and security teams

CVE-2012-2807 is an old libxml2 parsing flaw involving integer overflows on 64-bit Linux. A remote attacker could crash affected software, and the record leaves open unspecified other impact. The clearest named exposure is Google Chrome before 20.0.1132.43, with other libxml2-consuming products addressed by vendors. Exposure is most likely in legacy 64-bit Linux systems running vulnerable libxml2 packages or old products bundling libxml2, including Chrome before 20.0.1132.43. Current supported systems are less likely exposed if vendor security updates are applied. Treat this as a legacy hygiene issue unless vulnerable software remains in production. Prioritize internet-facing XML-processing services, unsupported Linux systems, and old bundled applications. There is no provided evidence of active exploitation, but vendor updates indicate real downstream exposure. Mitigation focus: Update libxml2 through the operating system or product vendor channel.; Upgrade Chrome beyond 20.0.1132.43, preferably to a supported current release.; Check Apple, SUSE, Ubuntu, Debian, and product-specific advisories for applicable fixed packages..
