Product Link: http://us.trendmicro.com/us/products/personal/internet-security/ ====================================================================== 4) Description of Vulnerability Secunia Research has discovered vulnerabilities in Trend Micro Network Security Component (NSC) modules as bundled with various products. These can be exploited by malicious, local users to cause a DoS (Denial of Service) or potentially gain escalated privileges. 1) Input validation errors exist in the firewall service (TmPfw.exe) within the "ApiThread()" function when processing packets sent to the service (by default port 40000/TCP). These can be exploited to cause heap-based buffer overflows via specially crafted packets containing a small value in a size field. Successful exploitation may allow execution of arbitrary code with SYSTEM privileges. 2) Input validation errors exist in the firewall service (TmPfw.exe) within the "ApiThread()" function when processing packets sent to the service (by default port 40000/TCP). These can be exploited to crash the service via specially crafted packets containing an overly large value in a size field. ====================================================================== 5) Solution Apply patch for OfficeScan 8.0 SP1 Patch 1. A fix for Trend Micro Internet Security should be available shortly. ====================================================================== 6) Time Table 17/10/2008 - Vendor notified. 18/10/2008 - Vendor response. 14/12/2008 - Vendor provides hotfix for testing. 19/12/2008 - Vendor informed that hotfix fixes vulnerabilities. 18/01/2009 - Vendor issues fix for OfficeScan 8.0 SP1 Patch 1. 20/01/2009 - Public disclosure. ====================================================================== 7) Credits Discovered by Carsten Eiram, Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned the following CVE identifiers: * CVE-2008-3864 (DoS via large size value) * CVE-2008-3865 (buffer overflow) Trend Micro: http://www.trendmicro.com/ftp/documentation/readme/ OSCE8.0_SP1_Patch1_CriticalPatch_3191_Readme.txt ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
