HTTP: McAfee VirusScan On-Access Scanner Long Unicode Filename Handling Buffer Overflow
This signature detects attempts to exploit a known vulnerability in McAfee VirusScan. It is due to a boundary error when processing overly long file names that contain Unicode characters. A remote attacker can exploit this vulnerability by placing a file with a specially crafted name on the target system and enticing the user to access the file. A successful attack can lead to arbitrary code execution.
Extended Description
McAfee VirusScan On-Access Scanner is prone to a filename-buffer-overflow vulnerability. The application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. A remote attacker may exploit this issue to execute arbitrary code on a vulnerable computer with SYSTEM privileges. Failed exploit attempts may disable the On-Access Scanner component of McAfee VirusScan. McAfee VirusScan On-Access Scanner 8.0i Enterprise Patch 11 and earlier versions are vulnerable to this issue.
