-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2002.566 -- RHSA-2002:207-14 Updated packages fix PostScript and PDF security issue 11 October 2002 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: gv ggv Vendor: Red Hat Operating System: Red Hat Linux 6.2 Red Hat Linux 7.0, 7.1, 7.2, 7.3 Red Hat Linux 8.0 Platform: Alpha i386 IA-64 SPARC Impact: Execute Arbitrary Code/Commands Access Required: Remote Ref: ESB-2002.554 - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated packages fix PostScript and PDF security issue Advisory ID: RHSA-2002:207-14 Issue date: 2002-09-23 Updated on: 2002-10-09 Product: Red Hat Linux Keywords: pdf adobe postscript exploit Cross references: Obsoletes: CVE Names: CAN-2002-0838 - --------------------------------------------------------------------- 1. Topic: Updated packages for gv and ggv fix a local buffer overflow when reading malformed PDF or PostScript(R) files. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 3. Problem description: Both gv and ggv are applications which use the Ghostscript PostScript interpreter to display PostScript and PDF documents under the X Window System. Zen Parse found a local buffer overflow in gv version 3.5.8 and earlier. Under this vulnerability, an attacker can create a carefully crafted, malformed PDF or PostScript file that, when viewed using gv, executes arbitrary commands on the system. Because ggv contains code derived from gv, it has the same vulnerability. All users of gv and ggv are advised to upgrade to these errata packages to correct this vulnerability. 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.
