libc security update

CentOS Errata and Security Advisory CESA-2005:848

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.
