The Computer Associates Anti-Virus engine contains a stack-based buffer overflow in the code responsible for processing CAB archives. Specifically, the Computer Associates Anti-Virus engine fails to properly validate the size of the file names contained in CAB archives. This may allow a stack-based buffer overflow to occur.

This vulnerability affects numerous Computer Associates products, including:

• CA Anti-Virus
• eTrust EZ Antivirus
• CA Internet Security Suite 2007
• eTrust Internet Security Suite
• eTrust EZ Armor
• CA Threat Manager
• CA Protection Suites
• CA Secure Content Manager
• CA Anti-Virus Gateway
• Unicenter Network and Systems Management
• BrightStor ARCserve Backup
• CA Common Services
• CA Anti-Virus SDK (formerly eTrust Anti-Virus SDK)

A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial-of-service condition..
