Synopsis:    Moderate: dovecot security update
Issue Date:  2011-08-18
CVE Numbers: CVE-2011-1929


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.
