7-Zip ARJ File Handling Overflow

This script is Copyright (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

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 an attacker 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 privileges.
