RHSA-2011:1811 - Important: netpbm security update

Synopsis

Important: netpbm security update

Type/Severity

Security Advisory Important

Topic

Updated netpbm packages that fix three security issues are now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having important 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.

Description

The netpbm packages contain a library of functions which support programs for handling various graphics file formats, including .pbm (Portable Bit Map), .pgm (Portable Gray Map), .pnm (Portable Any Map), .ppm (Portable Pixel Map), and others.

Two heap-based buffer overflow flaws were found in the embedded JasPer library, which is used to provide support for Part 1 of the JPEG 2000 image compression standard in the jpeg2ktopam and pamtojpeg2k tools. An attacker could create a malicious JPEG 2000 compressed image file that could cause jpeg2ktopam to crash or, potentially, execute arbitrary code with the privileges of the user running jpeg2ktopam. These flaws do not affect pamtojpeg2k. (CVE-2011-4516, CVE-2011-4517)

A stack-based buffer overflow flaw was found in the way the xpmtoppm tool processed X PixMap (XPM) image files. An attacker could create a malicious XPM file that would cause xpmtoppm to crash or, potentially, execute arbitrary code with the privileges of the user running xpmtoppm. (CVE-2009-4274)

Red Hat would like to thank Jonathan Foote of the CERT Coordination Center for reporting the CVE-2011-4516 and CVE-2011-4517 issues.

All users of netpbm are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
