—–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 die Mozilla Browser-Engine zum Rendern und
Darstellen von HTML-Inhalten.

CVE-2011-2983 – Schwachstelle in der Mozilla Browser-Engine

In der Mozilla Browser Engine wird nicht korrekter JavaScript-Code
unsicher behandelt, so dass Zugriffe auf bereits freigegebenen Speicher
stattfinden koennen. Ein entfernter Angreifer kann dies ausnutzen, um
mithilfe von praeparierten JavaScript-Inhalten die Anwendung, welche die
Browser Engine nutzt, zum Absturz zu bringen (Denial of Service) oder um
schlimmstenfalls beliebige Befehle mit den Rechten des Benutzers der
Anwendung zur Ausfuehrung zu bringen.

CVE-2011-2982 – Schwachstelle in der Mozilla Browser-Engine

In der Mozilla Browser-Engine bestehen mehrere, nicht naeher
beschriebene Fehler, welche unter bestimmten Umstaenden zu korrumpiertem
Speicher fuehren koennen. Ein Angreifer kann dies im schlimmsten Fall
ausnutzen, um beliebige Befehle mit den Rechten der Anwendung, welche
die Browser-Engine nutzt, zur Ausfuehrung zu bringen.

Betroffen sind die folgenden Software Pakete und Plattformen:

Paket seamonkey

SeaMonkey. (CVE-2011-2982)
