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.

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.
