Scientific Linux Security Update : cyrus-imapd on SL4.x, SL5.x, SL6.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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

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)

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