Red Hat Security Advisory: ghostscript security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2012:1256 Final 1 1 2012-09-11T18:08:00Z Current version 2012-09-11T18:08:00Z 2012-09-11T18:08:00Z Red Hat rhsa-to-cvrf 1.0.1484 2012-09-11T18:27:02Z Updated ghostscript packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link 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. An integer overflow flaw, leading to a heap-based buffer overflow, was found in Ghostscript's International Color Consortium Format library (icclib). An attacker could create a specially-crafted PostScript or PDF file with embedded images that would cause Ghostscript to crash or, potentially, execute arbitrary code with the privileges of the user running Ghostscript. (CVE-2012-4405) Red Hat would like to thank Marc Schönefeld for reporting this issue. Users of Ghostscript are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
