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.
