eTrust Antivirus Zip Archive Virus Detection Bypass Vulnerability

by Marianna Schmudlach / February 16, 2004 12:15 AM PST

Critical:
Moderately critical
Impact: Security Bypass

Where: From remote



Software: eTrust Antivirus 7.x for Windows NT/2000/XP




Description:
A vulnerability has been reported in eTrust Antivirus 7.0, allowing malware to bypass the virus detection.

The scanning engine doesn't handle ZIP archives containing password protected files correctly. The problem is that the scanning engine doesn't scan remaining files after a password protected file has been scanned, which allows an infected file to pass undetected.

Solution:
Apply patch for 0302 level (Build 139) or higher.
