RHSA-2009:1459 - Important: cyrus-imapd security update

Synopsis

Important: cyrus-imapd security update

Type/Severity

Security Advisory Important

Topic

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.

Description

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.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.http://kbase.redhat.com/faq/docs/DOC-11259
