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.

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.

The absence of Anti-CSRF tokens in Trend Micro ScanMail for Exchange 12.0 web interface forms could allow an attacker to submit authenticated requests when an authenticated user browses an attacker-controlled domain.

The Log Query and Quarantine Query pages in Trend Micro ScanMail for Exchange 12.0 are vulnerable to cross site scripting (XSS) attacks.

A vulnerability in Trend Micro ScanMail for Exchange 12.0 exists in which certain specific installations that utilize a uncommon feature - Other Update Sources - could be exploited to overwrite sensitive files in the ScanMail for Exchange directory.

A vulnerability in Trend Micro ScanMail for Exchange 12.0 exists in which some communications to the update servers are not encrypted.

Trend Micro ScanMail for Microsoft Exchange (SMEX) 10.2 before Hot Fix Build 3318 and 11.0 before Hot Fix Build 4180 creates session IDs for the web console using a random number generator with predictable values, which makes it easier for remote attackers to bypass authentication via a brute force attack.

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.

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 ScanMail allows remote attackers to obtain potentially sensitive information or disable the anti-virus capability via the smency.nsf file.
