--------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated unzip package fixes security issue Advisory ID: FLSA:180159 Issue date: 2006-04-04 Product: Red Hat Linux, Fedora Core Keywords: Bugfix, Security CVE Names: CVE-2005-4667 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: An updated unzip package that fixes a buffer overflow vulnerability is now available. The unzip utility is used to list, test, or extract files from a zip archive. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 Fedora Core 2 - i386 Fedora Core 3 - i386, x86_64 3. Problem description: A buffer overflow bug has been discovered in unzip when handling long file names. An attacker could create a specially crafted path which could cause unzip to crash or execute arbitrary instructions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-4667 to this issue. Users of unzip should upgrade to this updated package, which contains backported patches and is not vulnerable to 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.

Our key is available from http://www.fedoralegacy.org/about/security.php You can verify each package with the following command: rpm --checksig -v <filename> If you only wish to verify that each package has not been corrupted or tampered with, examine only the sha1sum with the following command: sha1sum <filename> 8.
