CentOS Errata and Security Advisory CESA-2011:1187
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.
