Attack: CuteZip .zip File Buffer Overflow Vulnerability

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempts to exploit a buffer overflow vulnerability in CuteZip which could result in remote code execution.

Additional Information

CuteZip is a file compression application.

The application is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Specifically, this issue occurs because the application fails to check the length of an archive when opening a specially crafted '.zip' file.

Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.


  • CuteZip 2.1 build 9.24.1 is vulnerable; other versions may also be affected.
