GPL Ghostscript: User-assisted execution of arbitrary code

Background

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

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"
