-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2004.0124 -- RHSA-2004:059-01 Updated XFree86 packages fix privilege escalation vulnerability 16 February 2004 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: XFree86 Publisher: Red Hat Operating System: Red Hat Linux 9 Impact: Root Compromise Access Required: Existing Account CVE Names: CAN-2004-0083 CAN-2004-0084 CAN-2004-0106 Ref: ESB-2004.0116 - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated XFree86 packages fix privilege escalation vulnerability Advisory ID: RHSA-2004:059-01 Issue date: 2004-02-13 Updated on: 2004-02-13 Product: Red Hat Linux Keywords: Cross references: Obsoletes: RHSA-2003:288 CVE Names: CAN-2004-0083 CAN-2004-0084 CAN-2004-0106 - - --------------------------------------------------------------------- 1. Topic: Updated XFree86 packages that fix a privilege escalation vulnerability are now available. 2. Relevant releases/architectures: Red Hat Linux 9 - i386 3. Problem description: XFree86 is an implementation of the X Window System, providing the core graphical user interface and video drivers. iDefense discovered two buffer overflows in the parsing of the 'font.alias' file. A local attacker could exploit this vulnerability by creating a carefully-crafted file and gaining root privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0083 and CAN-2004-0084 to these issues. Additionally David Dawes discovered additional flaws in reading font files. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0106 to these issues. All users of XFree86 are advised to upgrade to these erratum packages, which contain a backported fix and are not vulnerable to these issues. Red Hat would like to thank David Dawes from XFree86 for the patches and notification of 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 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. If up2date fails to connect to Red Hat Network due to SSL Certificate Errors, you need to install a version of the up2date client with an updated certificate. The latest version of up2date is available from the Red Hat FTP site and may also be downloaded directly from the RHN website: https://rhn.redhat.com/help/latest-up2date.pxt 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 76959 - applications recieve too many keyboard events from X 114901 - CAN-2004-0083 XFree86 font.alias overflow 6.
