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 OfficeScan client allows remote attackers to cause a denial of service by making 5 connections to port 12345, which raises CPU utilization to 100%.

Trend Micro OfficeScan allows remote attackers to replay administrative commands and modify the configuration of OfficeScan clients.

Vulnerability in cgiWebupdate.exe in Trend Micro OfficeScan Corporate Edition (aka Virus Buster) 3.5.2 through 3.5.4 allows remote attackers to read arbitrary files.

Trend Micro OfficeScan Corporate Edition (aka Virus Buster) 3.53 allows remote attackers to access sensitive information from the hotdownload directory without authentication, such as the ofcscan.ini configuration file, which contains a weakly encrypted password.

Buffer overflow in pop3trap.exe for PC-cillin 2000, 2002, and 2003 allows local users to execute arbitrary code via a long input string to TCP port 110 (POP3).

The default installation of Trend Micro OfficeScan 3.0 through 3.54 and 5.x allows remote attackers to bypass authentication from cgiChkMasterPasswd.exe and gain access to the web management console via a direct request to cgiMasterPwd.exe.

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.

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.

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.

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."

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.

The Trend Micro OfficeScan client tmlisten.exe allows remote attackers to cause a denial of service via malformed data to port 12345.
