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
