Descriptions

Multiple Sophos Anti-Virus products, including Anti-Virus for Windows 5.x before 5.2.1 and 4.x before 4.05, when cabinet file inspection is enabled, allows remote attackers to execute arbitrary code via a CAB file with "invalid folder count values," which leads to heap corruption.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Sophos AntiVirus. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the unpacking of Microsoft Cabinet files that contain invalid folder count values within the CAB header. Parsing of a specially crafted cabinet file can lead to an exploitable heap corruption. This vulnerability is only exposed when cabinet file inspection is explicitly enabled.
