SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2005:009 (cyrus-imapd).
This update fixes one-byte buffer overruns in the cyrus-imapd IMAP server package.
Several overruns were fixed in the IMAP annote extension as well as in cached header handling which can be run by an authenticated user.
