RHEL 4 / 5 : kdegraphics (RHSA-2009:0431)

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

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

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kdegraphics packages contain applications for the K Desktop
Environment, including KPDF, a viewer for Portable Document Format
(PDF) files.

Multiple integer overflow flaws were found in KPDF's JBIG2 decoder. An
attacker could create a malicious PDF file that would cause KPDF to
crash or, potentially, execute arbitrary code when opened.
(CVE-2009-0147, CVE-2009-1179)

Multiple buffer overflow flaws were found in KPDF's JBIG2 decoder. An
attacker could create a malicious PDF file that would cause KPDF to
crash or, potentially, execute arbitrary code when opened.
(CVE-2009-0146, CVE-2009-1182)

Multiple flaws were found in KPDF's JBIG2 decoder that could lead to
the freeing of arbitrary memory. An attacker could create a malicious
PDF file that would cause KPDF to crash or, potentially, execute
arbitrary code when opened. (CVE-2009-0166, CVE-2009-1180)

Multiple input validation flaws were found in KPDF's JBIG2 decoder. An
attacker could create a malicious PDF file that would cause KPDF to
crash or, potentially, execute arbitrary code when opened.
(CVE-2009-0800)

Multiple denial of service flaws were found in KPDF's JBIG2 decoder.
An attacker could create a malicious PDF that would cause KPDF to
crash when opened. (CVE-2009-0799, CVE-2009-1181, CVE-2009-1183)

Red Hat would like to thank Braden Thomas and Drew Yao of the Apple
Product Security team, and Will Dormann of the CERT/CC for responsibly
reporting these flaws.

Users are advised to upgrade to these updated packages, which contain
backported patches to resolve these issues.
