Amazon Linux AMI : cyrus-imapd (ALAS-2011-27)

high Nessus Plugin ID 69586


The remote Amazon Linux AMI host is missing a security update.


An authentication bypass flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to read or post newsgroup messages on an NNTP server configured to require user authentication, without providing valid authentication credentials. (CVE-2011-3372)

A NULL pointer dereference flaw was found in the cyrus-imapd IMAP server, imapd. A remote attacker could send a specially crafted mail message to a victim that would possibly prevent them from accessing their mail normally, if they were using an IMAP client that relies on the server threading IMAP feature. (CVE-2011-3481)


Run 'yum update cyrus-imapd' to update your system.
