An input validation vulnerability found in multiple Trend Micro products utilizing a particular version of a specific rootkit protection driver could allow an attacker in user-mode with administrator permissions to abuse the driver to modify a kernel address that may cause a system crash or potentially lead to code execution in kernel mode. An attacker must already have obtained administrator access on the target machine (either legitimately or via a separate unrelated attack) to exploit this vulnerability.

Trend Micro OfficeScan versions 11.0 and XG (12.0) could be exploited by an attacker utilizing a directory traversal vulnerability to extract files from an arbitrary zip file to a specific folder on the OfficeScan server, which could potentially lead to remote code execution (RCE). The remote process execution is bound to a web service account, which depending on the web platform used may have restricted permissions. An attempted attack requires user authentication.

Memory Corruption Privilege Escalation vulnerabilities in Trend Micro OfficeScan 11.0 and XG allows local attackers to execute arbitrary code and escalate privileges to resources normally reserved for the kernel on vulnerable installations by exploiting tmwfp.sys. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit the vulnerability.

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 headsize and packsize fields set to zero, which triggers an infinite loop.

Buffer overflow in PCCSRV\Webconsole\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.

Buffer overflow in PCCSRV\Webconsole\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.

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.

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.
