Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 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

3. Description:

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.

4. Solution:
