Summary: An updated tar package that fixes a buffer overflow bug is now available for Red Hat Enterprise Linux 4. This update has been rated as having Moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: The GNU tar program saves many files together in one archive and can restore individual files (or all of the files) from that archive. Jim Meyering discovered a buffer overflow bug in the way GNU tar extracts malformed archives. By tricking a user into extracting a malicious tar archive, it is possible to execute arbitrary code as the user running tar. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2006-0300 to this issue. Users of tar should upgrade to this updated package, which contains a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. 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.
