CVEs (cve.mitre.org): CVE-2008-0888

Details

Updated unzip packages that fix a security issue are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

The unzip utility is used to list, test, or extract files from a zip
archive.

An invalid pointer flaw was found in unzip. If a user ran unzip on a
specially crafted file, an attacker could execute arbitrary code with that
user's privileges. (CVE-2008-0888)

Red Hat would like to thank Tavis Ormandy of the Google Security Team for
reporting this issue.

All unzip users are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.
