Description


Tan Chew Keong has reported a vulnerability in PowerZip, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the handling of filenames in ZIP archives. This can be exploited to cause a stack-based buffer overflow when a malicious ZIP archive containing a file with an overly long filename is opened.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in version 7.06 Build 3895. Prior versions may also be affected.


Solution:
Update to version 7.07 Build 3901.
