RHEL 3 / 4 / 5 : star (RHSA-2007:0873)

Synopsis :

The remote Red Hat host is missing a security update.

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.

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.
