Fedora Legacy Update AdvisorySynopsis: Updated Xpdf package fixes security issues Advisory ID: FLSA:2352 Issue date: 2005-02-10 Product: Red Hat Linux, Fedora Core Keywords: Bugfix Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2352 CVE Names: CAN-2004-0888 CAN-2004-1125 CAN-2005-0064 ---------------------------------------------------------------------
--------------------------------------------------------------------- 1. Topic:
Updated Xpdf packages that fix several security issues are now available.
Xpdf is an X Window System based viewer for Portable Document Format (PDF) files.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386
3. Problem description:
During a source code audit, Chris Evans and others discovered a number of integer overflow bugs that affected all versions of xpdf. An attacker could construct a carefully crafted PDF file that could cause xpdf to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0888 to this issue.
A buffer overflow flaw was found in the Gfx::doImage function of Xpdf. An attacker could construct a carefully crafted PDF file that could cause Xpdf to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1125 to this issue.
A buffer overflow flaw was found when processing the /Encrypt /Length tag. An attacker could construct a carefully crafted PDF file that could cause Xpdf to crash or possibly execute arbitrary code when opened. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0064 to this issue.
Users of xpdf are advised to upgrade to these errata packages, which contain backported patches correcting these issues.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.
Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get.
