RHSA-2007:0873 - Security Advisory

Topic

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.

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.
