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

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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

A flaw was found in the way Dovecot handled SIGCHLD signals. If a
large amount of IMAP or POP3 session disconnects caused the Dovecot
master process to receive these signals rapidly, it could cause the
master process to crash. (CVE-2010-3780)

A flaw was found in the way Dovecot processed multiple Access Control
Lists (ACL) defined for a mailbox. In some cases, Dovecot could fail
to apply the more specific ACL entry, possibly resulting in more
access being granted to the user than intended. (CVE-2010-3707)

This update also adds the following enhancement :

- This erratum upgrades Dovecot to upstream version 2.0.9,
providing multiple fixes for the 'dsync' utility and
improving overall performance. Refer to the
'/usr/share/doc/dovecot-2.0.9/ChangeLog' file after
installing this update for further information about the
changes. (BZ#637056)

Users of dovecot are advised to upgrade to these updated packages,
which resolve these issues and add this enhancement. After installing
the updated packages, the dovecot service will be restarted
