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."
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
