RHEL 4 / 5 : cyrus-imapd (RHSA-2009:1116)

This script is Copyright (C) 2009-2017 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated cyrus-imapd packages that fix a security issue are now
available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The cyrus-imapd packages contain a high-performance mail server with
IMAP, POP3, NNTP, and SIEVE support.

It was discovered that the Cyrus SASL library (cyrus-sasl) does not
always reliably terminate output from the sasl_encode64() function
used by programs using this library. The Cyrus IMAP server
(cyrus-imapd) relied on this function's output being properly
terminated. Under certain conditions, improperly terminated output
from sasl_encode64() could, potentially, cause cyrus-imapd to crash,
disclose portions of its memory, or lead to SASL authentication
failures. (CVE-2009-0688)

Users of cyrus-imapd are advised to upgrade to these updated packages,
which resolve this issue. After installing the update, cyrus-imapd
will be restarted automatically.
