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.

Buffer overflow in PCCSRV\Web_console\RemoteInstallCGI\CgiRemoteInstall.exe for Trend Micro OfficeScan 7.3 before build 7.3.0.1089 allows remote attackers to execute arbitrary code via unknown attack vectors.

Buffer overflow in PCCSRV\Web_console\RemoteInstallCGI\Wizard.exe for Trend Micro OfficeScan 7.3 before build 7.3.0.1087 allows remote attackers to execute arbitrary code via unknown attack vectors.

Trend Micro OfficeScan 6.0 in Client/Server/Messaging (CSM) Suite for SMB 2.0 before 6.0.0.1385, and OfficeScan Corporate Edition (OSCE) 6.5 before 6.5.0.1418, 7.0 before 7.0.0.1257, and 7.3 before 7.3.0.1053 allow remote attackers to remove OfficeScan clients via a certain HTTP request that invokes the OfficeScan CGI program.

Trend Micro OfficeScan 6.0 in Client/Server/Messaging (CSM) Suite for SMB 2.0 before 6.0.0.1385, and OfficeScan Corporate Edition (OSCE) 6.5 before 6.5.0.1418, 7.0 before 7.0.0.1257, and 7.3 before 7.3.0.1053 allow remote attackers to delete files via a modified filename parameter in a certain HTTP request that invokes the OfficeScan CGI program.

Format string vulnerability in the ActiveX control (ATXCONSOLE.OCX) in TrendMicro OfficeScan Corporate Edition (OSCE) before 7.3 Patch 1 allows remote attackers to execute arbitrary code via format string identifiers in the "Management Console's Remote Client Install name search".

Trend Micro OfficeScan 5.5, and probably other versions before 6.5, uses insecure DACLs for critical files, which allows local users to gain SYSTEM privileges by modifying tmlisten.exe.

Multiple interpretation error in Trend Micro (1) PC-Cillin 2005 12.0.1244 with the 7.510.1002 engine and (2) OfficeScan 7.0 with the 7.510.1002 engine allows remote attackers to bypass virus scanning via a file such as BAT, HTML, and EML with an "MZ" magic byte sequence which is normally associated with EXE, which causes the file to be treated as a safe type that could still be executed as a dangerous file type by applications on the end system, as demonstrated by a "triple headed" program that contains EXE, EML, and HTML content, aka the "magic byte bug."

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.
