http://secunia.com/advisories/25959/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
EnjoySAP
http://secunia.com/product/14725/

DESCRIPTION:
Mark Litchfield has reported two vulnerabilities in EnjoySAP, which
can be exploited by malicious people to compromise a user's system.

1) A boundary error within the kweditcontrol.kwedit.1 (kwedit.dll)
ActiveX control when handling the "PrepareToPostHTML()" method can be
exploited to cause a stack-based buffer overflow by passing an overly
long string (around 1060 bytes) as argument to the affected method.

2) A boundary error within the rfcguisink.rfcguisink.1 ActiveX
control when handling the "LaunchGui()" method can be exploited to
cause a heap-based buffer overflow by passing an overly long string
(around 1800 bytes) as argument to the affected method.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
Update to the latest version.
