-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Low: unzip security and bug fix update Advisory ID: RHSA-2007:0203-02 Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0203.html Issue date: 2007-05-01 Updated on: 2007-05-01 Product: Red Hat Enterprise Linux Keywords: large file toctou CVE Names: CVE-2005-2475 CVE-2005-4667 - --------------------------------------------------------------------- 1. Summary: Updated unzip packages that fix two security issues and various bugs are now available. This update has been rated as having low 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 unzip utility is used to list, test, or extract files from a zip archive. A race condition was found in Unzip. Local users could use this flaw to modify permissions of arbitrary files via a hard link attack on a file while it was being decompressed (CVE-2005-2475) A buffer overflow was found in Unzip command line argument handling. If a user could be tricked into running Unzip with a specially crafted long file name, an attacker could execute arbitrary code with that user's privileges. (CVE-2005-4667) As well, this update adds support for files larger than 2GB. All users of unzip should upgrade to these updated packages, which contain backported patches that resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5.
