Trend Micro Officescan corporate_5.58

Buffer overflow in the Trend Micro Scan Engine 8.000 and 8.300 before virus pattern file 4.245.00, as used in other products such as Cyber Clean Center (CCC) Cleaner, allows remote attackers to execute arbitrary code via a malformed UPX compressed executable.

Heap-based buffer overflow in Trend Micro AntiVirus Library VSAPI before 7.510, as used in multiple Trend Micro products, allows remote attackers to execute arbitrary code via a crafted ARJ file with long header file names that modify pointers within a structure.

Trend OfficeScan Corporate Edition 5.58 and possibly earler does not drop privileges when opening a help window from a virus detection pop-up window, which allows local users to gain SYSTEM privileges.

Trend Micro OfficeScan 3.0 - 6.0 has default permissions of "Everyone Full Control" on the installation directory and registry keys, which allows local users to disable virus protection.
