TITLE

Trend Micro NSC Module Trend Micro Personal Firewall Vulnerabilities that prevent access restrictions on services

DESCRIPTION

The Trend Micro Personal Firewall service (aka TmPfw.exe) in Trend Micro Network Security Component (NSC) modules, as used in Trend Micro OfficeScan 8.0 SP1 Patch 1 and Internet Security 2007 and 2008 17.0.1224, relies on client-side password protection implemented in the configuration GUI, which allows local users to bypass intended access restrictions and change firewall settings by using a modified client to send crafted packets. Successful exploits may allow an attacker to crash an affected application, execute arbitrary code, or bypass security. These issues affect the following: Trend Micro OfficeScan Corporate Edition 8.0 SP1 Patch 1 Trend Micro Internet Security 2008 Trend Micro Internet Security Pro 2008 Trend Micro PC-cillin Internet Security 2007. These can be exploited to cause heap-based buffer overflows via specially crafted packets containing a small value in a size field. The vulnerabilities are confirmed in versions 16.10.1063 and 16.10.1079. Other versions may also be affected.
