[RedHat] Schwachstellen in Mozilla Seamonkey

—–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.

Mozilla Seamonkey nutzt zur Darstellung von HTML-Inhalten die Mozilla
Browser Engine.

CVE-2011-0059 – Schwachstelle im Firefox Browser

Der Firefox Browser reagiert fehlerhaft, wenn ein Plug-in eine HTML 307
Antwort (redirect response) auf eine selbst initierte HTML-Anfrage
erhaelt. Als Folge des Fehlers wird unter Umstaenden Script-Code im
Kontext einer anderen Seite ausgefuehrt (Cross-Domain Scripting).

CVE-2011-0051 – Schwachstelle in Mozilla Browser Engine bei der
Darstellung von Dialog-Boxes

In der Mozilla Browser Engine ist ein Sicherheitsproblem bei der
Darstellung von Dialog-Boxen vorhanden, das dann auftritt, wenn der
Browser in einen inkonsistenten Zustand gebracht wird. Dies ist der
Fall, wenn eval()-Anweisungen rekursiv aufgerufen werden, die in ein
try/catch Statement eingebunden sind. Ein entfernter Angreifer kann
diese Schwachstelle ausnutzen, um den Benutzer ohne dessen Wissen zur
Akzeptanz einer Dialog-Box zu bringen.

CVE-2011-0053 / CVE-2011-0062 – Schwachstellen in der Mozilla Browser
Engine

In der Mozilla Browser Engine sind mehrere Schwachstellen vorhanden, die
zu der Verletzung von Speicherstrukturen fuehren koennen. Ein entfernter
Angreifer kann diese Schwachstellen ausnutzen, um den Browser zum
Absturz zu bringen. Eventuell ist die Ausfuehrung beliebiger Befehle
moeglich.

Betroffen sind die folgenden Software Pakete und Plattformen:

=====================================================================

1. Summary:

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 – i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 – i386, x86_64
Red Hat Enterprise Linux ES version 4 – i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 – i386, ia64, x86_64

3. Description:

SeaMonkey is an open source web browser, email and newsgroup client, IRC
chat client, and HTML editor.

A flaw was found in the way SeaMonkey handled dialog boxes. An attacker
could use this flaw to create a malicious web page that would present a
blank dialog box that has non-functioning buttons. If a user closes the
dialog box window, it could unexpectedly grant the malicious web page
elevated privileges. (CVE-2011-0051)

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2011-0053)

A flaw was found in the way SeaMonkey handled plug-ins that perform HTTP
requests. If a plug-in performed an HTTP request, and the server sent a 307
redirect response, the plug-in was not notified, and the HTTP request was
forwarded. The forwarded request could contain custom headers, which could
result in a Cross Site Request Forgery attack. (CVE-2011-0059)

All SeaMonkey users should upgrade to these updated packages, which correct
these issues. After installing the update, SeaMonkey must be restarted for
the changes to take effect.
