Synopsis
========

An integer overflow in GPL Ghostscript may allow remote attackers to
execute arbitrary code.

Background
==========

Ghostscript is an interpreter for the PostScript language and for PDF.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/ghostscript-gpl
< 9.09 >= 9.09

Description
===========

An integer overflow flaw was discovered that leads to an out-of-bounds
read and write in gs_ttf.ps.

Impact
======

A remote attacker could entice a user to open a specially crafted file,
possibly resulting in the execution of arbitrary code with the
privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All GPL Ghostscript users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=app-text/ghostscript-gpl-9.09"

References
