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 "Enabled scanning of archives" is set, allows remote attackers to cause a denial of service (infinite loop) via a malformed RAR archive with an Archive Header section with the head_size and pack_size fields set to zero.

Security readout for executives and security teams

This vulnerability lets a malformed RAR archive make affected Sophos antivirus scanners loop indefinitely when archive scanning is enabled. The business impact is availability: security scanning may stall or consume resources, potentially affecting endpoints, servers, or mail/file scanning workflows using vulnerable Sophos versions. Exposure is most likely in legacy Sophos deployments that still scan archives, especially mail gateways, file servers, Linux servers, or endpoints processing untrusted compressed files. Modern supported Sophos versions are not identified as affected in the provided sources. Prioritize remediation where legacy Sophos systems inspect untrusted archives in business-critical paths. This is not shown as exploited or code-execution capable, but a scanner denial of service can weaken protection and disrupt operations. 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 platform versions to 4.11 or later..
