Synopsis

Important: xpdf security update

Type/Severity

Security Advisory: Important

Topic

An updated xpdf package that fixes multiple security issues is now
available for Red Hat Enterprise Linux 3 and 4.

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

Description

Xpdf is an X Window System based viewer for Portable Document Format (PDF)
files.

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

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

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

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

Multiple denial of service flaws were found in Xpdf's JBIG2 decoder. An
attacker could create a malicious PDF that would cause Xpdf 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 this updated package, which contains
backported patches to correct these issues.
