Synopsis :

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

Description :

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)
