This signature detects an attempt to exploit a buffer overflow vulnerability in TUGZip application.
TUGZip is a file-archiving application for Microsoft Windows platforms.
The application is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. The vulnerability occurs when handling specially crafted ZIP files.
An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition.
