Sophos Anti-Virus and Endpoint Security before 6.0.5, Anti-Virus for Linux before 5.0.10, and other platforms before 4.11 allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via a malformed CHM file with a large name length in the CHM chunk header, aka "CHM name length memory consumption vulnerability."

Security readout for executives and security teams

This old Sophos antivirus flaw can make vulnerable scanning software crash and may allow code execution when it inspects a specially malformed CHM file. The main business concern is legacy exposure: systems still running pre-2006 fixed Sophos versions could fail while processing malicious files. Likely exposure is limited to organizations retaining very old Sophos antivirus products or appliances. Check endpoints, file servers, mail gateways, and Linux scanning hosts that may still process CHM files using outdated Sophos engines. Prioritize remediation if any legacy Sophos deployment remains in production. Modern environments are unlikely to be exposed, but obsolete antivirus software processing untrusted files creates disproportionate operational and security risk. Mitigation focus: Upgrade Sophos Anti-Virus and Endpoint Security to 6.0.5 or later.; Upgrade Sophos Anti-Virus for Linux to 5.0.10 or later.; Upgrade other affected Sophos platforms to 4.11 or later..
