SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated 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.
SolutionUpdate the affected cyrus-imapd packages.
