Trend Micro's Virus Scan API (VSAPI) and Advanced Threat Scan Engine (ATSE) - are vulnerable to a memory exhaustion vulnerability that may lead to denial-of-service or system freeze if exploited by an attacker using a specially crafted file.

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 has repackaged installers for several Trend Micro products that were found to utilize a version of an install package that had a DLL hijack vulnerability that could be exploited during a new product installation. The vulnerability was found to ONLY be exploitable during an initial product installation by an authorized user. The attacker must convince the target to download malicious DLL locally which must be present when the installer is run.

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 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.

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.
