imap security update

CentOS Errata and Security Advisory CESA-2005:850

The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access protocols.

A buffer overflow flaw was discovered in the way the c-client library
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 the library. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-2933 to this issue.

All users of imap should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
