Descripción:	Summary: The remote host is missing an update for the 'dovecot' package(s) announced via the referenced advisory. Vulnerability Insight: 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 automatically. Affected Software/OS: dovecot on Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages.
