Synopsis
=======

Adobe Acrobat Reader is vulnerable to a buffer overflow that could lead to remote execution of arbitrary code.

Background
=========

Adobe Acrobat Reader is a utility used to view PDF files.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/acroread lt;= 5.10 gt;= 7.0

Description
==========

A buffer overflow has been discovered in the UnixAppOpenFilePerform() function, which is called when Adobe Acrobat Reader tries to open a file with the "\\Filespec" tag.

Impact
=====

By enticing a user to open a specially crafted PDF document, a remote attacker could exploit this vulnerability to execute arbitrary code.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

Since Adobe will most likely not update the 5.0 series of Adobe Acrobat Reader for Linux, all users should upgrade to the latest available version of the 7.0 series:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=app-text/acroread-7.0"
