[RedHat] Schwachstelle in Cyrus IMAPD

—–BEGIN PGP SIGNED MESSAGE—–
Hash: SHA1

Liebe Kolleginnen und Kollegen,

soeben erreichte uns nachfolgendes RedHat Security Advisory. Wir geben
diese Informationen unveraendert an Sie weiter.

CVE-2011-3208 – Schwachstelle in Cyrus-IMAP (nntp)

In der Cyrus-Komponente ‘nntp’ in der Datei imap/nntpd.c kann ein Buffer
Overflow ausgeloest werden. Ein entfernter Angreifer kann dies
ausnutzen, um schlimmstenfalls beliebigen Code auszufuehren oder die
Komponente zum Absturz zu bringen. Eine Authentifizierung zur
Durchfuehrung des Angriffs ist dabei nur notwendig, falls die Option
‘allowanonymouslogin’ nicht gesetzt wurde. Falls das Programm mit der
FORTIFY_SOURCE-Option kompiliert wurde, was beispielsweise Standard fuer
RHEL 5/6 und Fedora ist, kann allerdings die Schwachstelle nicht zur
Code-Ausfuehrung ausgenutzt werden.

Betroffen sind die folgenden Software Pakete und Plattformen:

Paket cyrus-imapd

RHEL Desktop Workstation (v. 5 client) – i386, x86_64
Red Hat Enterprise Linux (v. 5 server) – i386, ia64, ppc, s390x,

3. Description:

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.

4. 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
