cyrus, perl security update

CentOS Errata and Security Advisory CESA-2009:1459

The cyrus-imapd packages contain a high-performance mail server with IMAP,
POP3, NNTP, and Sieve support.

Multiple buffer overflow flaws were found in the Cyrus IMAP Sieve
implementation. An authenticated user able to create Sieve mail filtering
rules could use these flaws to execute arbitrary code with the privileges
of the Cyrus IMAP server user. (CVE-2009-2632, CVE-2009-3235)

Users of cyrus-imapd are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues. After installing
the update, cyrus-imapd will be restarted automatically.
