Attack: NetZIP Classic ZIP Parsing

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 NetZip Classic.

Additional Information

Netzip Classic is an application used for handling archive files.

Netzip Classic is prone to a buffer-overflow vulnerability because the software fails to perform adequate boundary checks on user-supplied data. Specifically, the issue occurs when parsing specially crafted '.zip' files.

Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the vulnerable application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects Netzip Classic; other versions may also be affected.
