Marshal MailMarshal ARJ Extraction Directory Traversal
------------------------------------------------------------------------


SUMMARY

This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Marshal MailMarshal (formerly of NetIQ).
Authentication is not required to exploit this vulnerability.

DETAILS

The specific flaw exists within the extraction and scanning of ARJ
compressed attachments. Due to incorrect sandboxing of extracted filenames
that contain directory traversal modifiers such as "../", an attacker can
cause an executable to be created in an arbitrary location.

While currently existing files can not be over written, an attacker may
leverage this vulnerability in a number of ways. For example, by placing a
malicious binary in the "all users" startup folder.

Vendor Response:
Marshal has issued an update to correct this vulnerability. More details
