7-Zip ARJ File Overflow Vulnerability

Vulnerability Assessment Summary
Checks version of arj.dll from 7-Zip

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote Windows host contains a library that is affected by a
buffer overflow vulnerability.

Description :

The remote host contains a version of the open-source 7-Zip file
archiver and included in third-party products such as Knownsoft's
Turbo Searcher.

The version of this software installed on the remote host contains a
buffer overflow in its ARJ file handling library that is triggered
when handling an ARJ block greater than 2600 bytes. If a possible hacker
can trick a user on the affected host into opening a specially-crafted
ARJ archive file, he can leverage this issue to execute arbitrary code
on the host subject to the user's rights.
