Scientific Linux Security Update : dovecot on SL4.x, SL5.x, SL6.x i386/x86_64

Synopsis :

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

Description :

Dovecot is an IMAP server for Linux, UNIX, and similar operating
systems, primarily written with security in mind.

A denial of service flaw was found in the way Dovecot handled NULL
characters in certain header names. A mail message with
specially-crafted headers could cause the Dovecot child process
handling the target user's connection to crash, blocking them from
downloading the message successfully and possibly leading to the
corruption of their mailbox. (CVE-2011-1929)

Users of dovecot are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue. After
installing the updated packages, the dovecot service will be restarted
automatically.
