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 coffFiles field in CAB archives before it is copied to a stack buffer. 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..

According to the Computer Associates Security Notice issued June 5th, 2007:

CA has issued content update 30.6 to address the vulnerabilities. The updated engine is provided with content updates. Ensure the latest content update is installed if the signature version is less than version 30.6.
