CVE-2007-2864

TITLE

Computer Associates Anti-Virus engine fails to properly handle long file names in CAB archives

DESCRIPTION

Stack-based buffer overflow in the Anti-Virus engine before content update 30.6 in multiple CA (formerly Computer Associates) products allows remote attackers to execute arbitrary code via a large invalid value of the coffFiles field in a .CAB file. There are several affected products. Large values result in an unbounded data copy operation which can result in an exploitable stack-based buffer overflow. Computer Associates is the world's leading security vendor, products include a variety of anti-virus software and backup recovery systems. CA has issued an update to address the vulnerabilities. The first vulnerability, CVE-2007-2863, is due to insufficient bounds checking on filenames contained in a CAB archive. The second vulnerability, CVE-2007-2863, is due to insufficient bounds checking on the "coffFiles" field. By using a specially malformed CAB file, an attacker can cause a crash or take unauthorized action on an affected system. Mitigating Factors: None Severity: CA has given these vulnerabilities a High risk rating. Affected Products: CA Anti-Virus for the Enterprise (formerly eTrust Antivirus) r8, r8.1 CA Anti-Virus 2007 (v8) eTrust EZ Antivirus r7, r6.1 CA Internet Security Suite 2007 (v3) eTrust Internet Security Suite r1, r2 eTrust EZ Armor r1, r2, r3.x CA Threat Manager for the Enterprise (formerly eTrust Integrated Threat Management) r8 CA Protection Suites r2, r3 CA Secure Content Manager (formerly eTrust Secure Content Manager) 8.0 CA Anti-Virus Gateway (formerly eTrust Antivirus eTrust Antivirus Gateway) 7.1 Unicenter Network and Systems Management (NSM) r3.0 Unicenter Network and Systems Management (NSM) r3.1 Unicenter Network and Systems Management (NSM) r11 Unicenter Network and Systems Management (NSM) r11.1 BrightStor ARCserve Backup r11.5 BrightStor ARCserve Backup r11.1 BrightStor ARCserve Backup r11 for Windows BrightStor Enterprise Backup r10.5 BrightStor ARCserve Backup v9.01 CA Common Services CA Anti-Virus SDK (formerly eTrust Anti-Virus SDK) Affected Platforms: All Status and Recommendation: CA has issued content update 30.6 to address the vulnerabilities.
