Security Advisory libc-client security update

Advisory: RHSA-2005:848-6
Type: Security Advisory
Severity: Moderate
Issued on: 2005-12-06
Last updated on: 2005-12-06
Affected Products: Red Hat Desktop (v. 4)
Red Hat Enterprise Linux AS (v. 4)
Red Hat Enterprise Linux ES (v. 4)
Red Hat Enterprise Linux WS (v. 4)
CVEs (cve.mitre.org): CVE-2005-2933

Details

Updated libc-client packages that fix a buffer overflow issue are now
available.

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

C-client is a common API for accessing mailboxes.

A buffer overflow flaw was discovered in the way C-client parses user
supplied mailboxes. If an authenticated user requests a specially crafted
mailbox name, it may be possible to execute arbitrary code on a server that
uses C-client to access mailboxes. The Common Vulnerabilities and Exposures
project has assigned the name CVE-2005-2933 to this issue.

All users of libc-client should upgrade to these updated packages, which
contain a backported patch that resolves this issue.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network. To use Red Hat Network,
