Advisory ID: RHSA-2006:0195-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0195.html
Issue date: 2006-02-21
Updated on: 2006-02-21
Product: Red Hat Enterprise Linux
CVE Names: CVE-2005-1918

1. Summary:
An updated tar package that fixes a path traversal flaw is 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 (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
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - 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.
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). Red Hat included a backported security patch to correct
this issue in Red Hat Enterprise Linux 3, and an erratum for Red Hat
Enterprise Linux 2.1 users was issued.
During internal testing, we discovered that our 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 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
