-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2003.0076 -- RHSA-2003:037-09 Updated Xpdf packages fix security vulnerability 07 February 2003 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Xpdf Vendor: Red Hat Operating System: Red Hat Linux 6.2 Red Hat Linux 7.0 Red Hat Linux 7.1 Red Hat Linux 7.2 Red Hat Linux 7.3 Red Hat Linux 8.0 Linux Platform: i386 IA-64 Impact: Execute Arbitrary Code/Commands Access Required: Remote Ref: ESB-2003.0010 Comment: CVE Id: CAN-2002-1384 - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated Xpdf packages fix security vulnerability Advisory ID: RHSA-2003:037-09 Issue date: 0000-01-01 Updated on: 2003-02-06 Product: Red Hat Linux Keywords: Cross references: Obsoletes: RHSA-2000:060 CVE Names: CAN-2002-1384 - --------------------------------------------------------------------- 1. Topic: Updated Xpdf packages are now available that fix a vulnerability in which a maliciously-crafted pdf document could run arbitrary code. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386 Red Hat Linux 7.0 - i386 Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem description: Xpdf is a viewer for Portable Document Format (PDF) files. During an audit of CUPS, a printing system, Zen Parsec found an integer overflow vulnerability in the pdftops filter. Since the code for pdftops is taken from the Xpdf project, all versions of Xpdf including 2.01 are also vulnerable to this issue. An attacker could create a PDF file that could execute arbitrary code. This could would have the same access privileges as the user who viewed the file with Xpdf. All users of Xpdf are advised to upgrade to these erratum packages. For Red Hat Linux 8.0 we have included new packages based on Xpdf 1.01 with a patch to correct this issue. For Red Hat Linux 7.0, 7.1, 7.2, and 7.3 we have upgraded Xpdf to version 1.00 with a patch to correct this issue. For Red Hat Linux 6.2 we have upgraded Xpdf to version 0.92 with a patch to correct this issue. 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 Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
