1.31.1. RHSA-2009:1459: Important security update

Important

This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:1459
Updated cyrus-imapd packages that fix several security issues 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.
Multiple buffer overflow flaws were found in the Cyrus IMAP Sieve implementation. An authenticated user able to create Sieve mail filtering rules could use these flaws to execute arbitrary code with the privileges of the Cyrus IMAP server user. (CVE-2009-2632, CVE-2009-3235)
Users of cyrus-imapd are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing the update, cyrus-imapd will be restarted automatically.
