Heap-based buffer overflow in Sophos Anti-Virus and Endpoint Security before 6.0.5, Anti-Virus for Linux before 5.0.10, and other platforms before 4.11, when archive scanning is enabled, allows remote attackers to trigger a denial of service (memory corruption) via a CHM file with an LZX decompression header that specifies a Window_size of 0.

Security readout for executives and security teams

This issue could let a crafted CHM archive crash vulnerable Sophos antivirus scanning when archive scanning is enabled. The main confirmed business risk is denial of service or memory corruption in a security control, not confirmed system takeover. Older Sophos deployments should be checked and upgraded. Exposure is most likely where legacy Sophos antivirus products still scan archives, especially CHM files arriving by email, web download, file share, or endpoint storage. The source bundle does not provide CPEs or complete platform inventory details. Treat this as a legacy exposure cleanup item unless unsupported Sophos versions are still deployed. Prioritize environments where antivirus availability is operationally important or where CHM files can reach endpoints or scanning gateways. 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 versions after 4.11..
