--------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated tar package fixes security issue Advisory ID: FLSA:183571-1 Issue date: 2006-04-04 Product: Red Hat Linux, Fedora Core Keywords: Bugfix, Security CVE Names: CVE-2005-1918 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: An updated tar package that fixes a path traversal flaw is now available. The GNU tar program saves many files together in one archive and can restore individual files (or all of the files) from that archive. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 Fedora Core 2 - i386 3. Problem description: In 2002, a path traversal flaw was found in the way GNU tar extracted archives. A malicious user could create a tar archive that could write to arbitrary files to which the user running GNU tar has write access (CVE-2002-0399). A security advisory was released containing a backported patch. It was discovered that the backported security patch contained an incorrect optimization and therefore was not sufficient to completely correct this vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-1918 to this issue. Users of tar should upgrade to this updated package, which contains a replacement 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. 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www.fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.
