Vulnerability Note VU#276432
Trend Micro AntiVirus fails to properly process malformed UPX packed executables
The Trend Micro AntiVirus scanning engine contains a buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Trend Micro AntiVirus is a virus scanner for Microsoft Windows and Linux. The Trend Micro virus scanning engine is included with Trend Micro security suites and other AntiVirus products. UPX is an open source packer for several executable formats. Malicious code is known to be compressed with UPX to avoid detection.
A buffer overflow vulnerability exists in Trend Micro AntiVirus that may occur when the scanning engine processes a malformed UPX archived file. If a specially crafted, UPX packed executable is scanned by Trend Micro, this vulnerability may be triggered.
A remote, unauthenticated attacker may be able to execute arbitrary code with kernel level privileges, or create a denial-of-service condition.
