RHEL 4 : ghostscript (RHSA-2012:0096)

Medium Nessus Plugin ID 57823


The remote Red Hat host is missing one or more security updates.


Updated ghostscript packages that fix two security issues are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language) and an interpreter for Portable Document Format (PDF) files.

Ghostscript included the current working directory in its library search path by default. If a user ran Ghostscript without the '-P-' option in an attacker-controlled directory containing a specially crafted PostScript library file, it could cause Ghostscript to execute arbitrary PostScript code. With this update, Ghostscript no longer searches the current working directory for library files by default.

Note: The fix for CVE-2010-4820 could possibly break existing configurations. To use the previous, vulnerable behavior, run Ghostscript with the '-P' option (to always search the current working directory first).

A flaw was found in the way Ghostscript interpreted PostScript Type 1 and PostScript Type 2 font files. An attacker could create a specially crafted PostScript Type 1 or PostScript Type 2 font file that, when interpreted, could cause Ghostscript to crash or, potentially, execute arbitrary code. (CVE-2010-4054)

Users of Ghostscript are advised to upgrade to these updated packages, which contain backported patches to correct these issues.


Update the affected ghostscript, ghostscript-devel and / or ghostscript-gtk packages.
