Fedora Legacy Update Advisory

Synopsis: Updated imap packages fix security issue
Advisory ID: FLSA:170411
Issue date: 2006-04-04
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix, Security
CVE Names: CVE-2005-2933
---------------------------------------------------------------------



---------------------------------------------------------------------
1. Topic:

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

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

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

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.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
