Detail

Problem Description:

An updated star 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 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 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 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

Star is a tar-like archiver. It saves multiple files into a single tape or disk archive, and can restore individual files from the archive. Star includes multi-volume support, automatic archive format detection and ACL support.

A path traversal flaw was discovered in the way star extracted archives. A malicious user could create a tar archive that would cause star to write to arbitrary files to which the user running star had write access. (CVE-2007-4134)

Red Hat would like to thank Robert Buchholz for reporting this issue.

As well, this update adds the command line argument "-.." to the Red Hat Enterprise Linux 3 version of star. This allows star to extract files containing "/../" in their pathname.

Users of star should upgrade to this updated package, which contain backported patches to correct these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188
