1. Summary:

Updated tar package that fixes a path traversal flaw is now available.

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

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.

A path traversal flaw was discovered 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 had write access. (CVE-2007-4131)

Red Hat would like to thank Dmitry V. Levin for reporting this issue.

Users of tar should upgrade to this updated package, which contains a
replacement backported patch to correct this issue.
