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