RHSA-2005:850 - Security Advisory

Topic

An updated imap package that fixes a buffer overflow issue is now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

The imap package provides server daemons for both the IMAP (Internet
Message Access Protocol) and POP (Post Office Protocol) mail access protocols.

A buffer overflow flaw was discovered in the way the c-client library
parses user supplied mailboxes. If an authenticated user requests a
specially crafted mailbox name, it may be possible to execute arbitrary
code on a server that uses the library. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-2933 to this issue.

All users of imap should upgrade to these updated packages, which contain a
backported patch and are not vulnerable to this issue.
