Red Hat Enterprise Linux: RHSA-2011:1317 Important Buffer Overflow Fix

red hat
Calendar Grey September 19, 2011
Scroller Redhat
Vital cyrus-imapd patch for Red Hat Enterprise Linux addresses a buffer overflow issue affecting email functionality. Immediate upgrade advised.
Updated cyrus-imapd packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and Sieve support.
A buffer overflow flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to crash the nntpd child process or, possibly, execute arbitrary code with the privileges of the cyrus user. (CVE-2011-3208)
Red Hat would like to thank Greg Banks for reporting this issue.
Users of cyrus-imapd are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, cyrus-imapd will be restarted automatically.
