Beschreibung:
Eine Sicherheitslücke in Trend Micros Scan-Engine wurde gemeldet, die böswillige lokale Benutzer ausnutzen können, um erweiterte Rechte zu erlangen.

Ein Begrenzungsfehler innerhalb des "0xa0284403"-IOCTL-Handlers von Tmxpflt.sys und unsichere Rechte auf dem DOS-Gerät "\\.\Tmfilter" können ausgenutzt werden, um z.B. einen Pufferüberlauf zu verursachen, indem man überlange Argumente an den betroffenen IOCTL-Handler übergibt.

Eine erfolgreiche Ausnutzung ermöglicht die Ausführung von beliebigem Code mit Kernel-Rechten.

Die Sicherheitslücke betrifft alle Produkte, die den Scan-Engine-Filter verwenden.

Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.

Lösung:
Aktualisieren Sie auf Scan-Engine 8.550-1001 (verfügbar via ActiveUpdate-Server am 30. Oktober 2007).
