-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2004.0088 -- RHSA-2004:056-01 Updated util-linux packages fix information leak 04 February 2004 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: util-linux Publisher: Red Hat Operating System: Red Hat Linux AW 2.1 Red Hat Enterprise Linux AS 2.1 Red Hat Enterprise Linux WS 2.1 Red Hat Enterprise Linux ES 2.1 Platform: IA-64 IA-32 Impact: Reduced Security CVE Names: CAN-2004-0080 - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated util-linux packages fix information leak Advisory ID: RHSA-2004:056-01 Issue date: 2004-01-30 Updated on: 2004-02-02 Product: Red Hat Enterprise Linux Keywords: Cross references: Obsoletes: CVE Names: CAN-2004-0080 - - --------------------------------------------------------------------- 1. Topic: Updated util-linux packages that fix an information leak in the login program are now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: The util-linux package contains a large variety of low-level system utilities that are necessary for a Linux system to function. In some situations, the login program could use a pointer that had been freed and reallocated. This could cause unintentional data leakage. Note: Red Hat Enterprise Linux 3 is not vulnerable to this issue. It is recommended that all users upgrade to these updated packages, which are not vulnerable to this issue. Red Hat would like to thank Matthew Lee of Fleming College for finding and reporting 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. 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.
