An updated tar package that fixes a buffer overflow bug is now available
for Red Hat Enterprise Linux 4.
This update has been rated as having Moderate security impact by the Red
Hat Security Response Team.
The GNU tar program saves many files together in one archive and can
restore individual files (or all of the files) from that archive.
Jim Meyering discovered a buffer overflow bug in the way GNU tar extracts
malformed archives. By tricking a user into extracting a malicious tar
archive, it is possible to execute arbitrary code as the user running tar.
The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned
the name CVE-2006-0300 to this issue.
Users of tar should upgrade to this updated package, which contains a
backported patch to correct this issue.
