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.

The Trend Micro scan engine before 8.320 for Windows and before 8.150 on HP-UX and AIX, as used in Trend Micro PC Cillin - Internet Security 2006, Office Scan 7.3, and Server Protect 5.58, allows remote attackers to cause a denial of service (CPU consumption and system hang) via a malformed RAR archive with an Archive Header section with the head_size and pack_size fields set to zero, which triggers an infinite loop.

Trend Micro PC-cillin Internet Security 2006 14.00.1485 and 14.10.0.1023, uses insecure DACLs for critical files, which allows local users to gain SYSTEM privileges by modifying executable programs such as (1) tmntsrv.exe and (2) tmproxy.exe.
