Amazon Linux AMI Security Advisory: ALAS-2011-27
Advisory Release Date: 2014-09-14 15:06 Pacific
Severity: Medium

Issue Overview:

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 )
