CVE-2007-3875

TITLE

CA Anti-Virus Such as arclib.dll Service disruption in (DoS) Vulnerabilities

DESCRIPTION

arclib.dll before 7.3.0.9 in CA Anti-Virus (formerly eTrust Antivirus) 8 and certain other CA products allows remote attackers to cause a denial of service (infinite loop and loss of antivirus functionality) via an invalid "previous listing chunk number" field in a CHM file. Multiple Computer Associates products are prone to a denial-of-service vulnerability because the applications fail to handle malformed CHM files. Successfully exploiting this issue will cause the affected applications to stop responding, denying service to legitimate users. This issue affects applications that use the 'arclib.dll' library versions prior to 7.3.0.9. The Arclib.DLL library in eTrust products has a security vulnerability. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Title: [CAID 35525, 35526]: CA Products Arclib Library Denial of Service Vulnerabilities CA Vuln ID (CAID): 35525, 35526 CA Advisory Date: 2007-07-24 Reported By: CVE-2006-5645 - Titon of BastardLabs and Damian Put <pucik at overflow dot pl> working with the iDefense VCP. CVE-2007-3875 - An anonymous researcher working with the iDefense VCP. Sergio Alvarez of n.runs AG also reported these issues. Impact: A remote attacker can cause a denial of service. Summary: CA products that utilize the Arclib library contain two denial of service vulnerabilities. The second vulnerability, CVE-2006-5645, is due to an application hang when processing a specially malformed RAR file. Mitigating Factors: None Severity: CA has given these vulnerabilities a Medium risk rating. Affected Products: CA Anti-Virus for the Enterprise (formerly eTrust Antivirus) 7.0, 7.1, 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 Anti-Virus Gateway (formerly eTrust Antivirus eTrust Antivirus Gateway) 7.1 CA Protection Suites r2, r3 CA Secure Content Manager (formerly eTrust Secure Content Manager) 1.1, 8.0 CA Anti-Spyware for the Enterprise (Formerly eTrust PestPatrol) r8, 8.1 CA Anti-Spyware 2007 Unicenter Network and Systems Management (NSM) r3.0, r3.1, r11, r11.1 BrightStor ARCserve Backup v9.01, r11 for Windows, r11.1, r11.5 BrightStor Enterprise Backup r10.5 BrightStor ARCserve Client agent for Windows eTrust Intrusion Detection 2.0 SP1, 3.0, 3.0 SP1 CA Common Services (CCS) r11, r11.1 CA Anti-Virus SDK (formerly eTrust Anti-Virus SDK) Status and Recommendation: CA has provided an update to address the vulnerabilities.

Using Windows Explorer, locate the file “arclib.dll”. By default, the file is located in the “C:\Program Files\CA\SharedComponents\ScanEngine” directory(*). 2. Right click on the file and select Properties. 3. Select the Version tab. 4. If the file version is earlier than indicated in the table below, the installation is vulnerable. File Name File Version arclib.dll 7.3.0.9 *For eTrust Intrusion Detection 2.0 the file is located in “Program Files\eTrust\Intrusion Detection\Common”, and for eTrust Intrusion Detection 3.0 and 3.0 sp1, the file is located in “Program Files\CA\Intrusion Detection\Common”. For CA Anti-Virus r8.1 on non-Windows: Use the compver utility provided on the CD to determine the version of arclib.dll. The same version information above applies.
