TITLE:

SECUNIA ADVISORY ID:
SA25156

VERIFY ADVISORY:
http://secunia.com/advisories/25156/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
HTTP File Upload ActiveX Control 6.x
http://secunia.com/product/14140/

DESCRIPTION:
shinnai has discovered a vulnerability in HTTP File Upload ActiveX
Control, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error within the File
upload ActiveX Control (UFileUploaderD.dll) when processing arguments
passed to the "AddFile()" method. This can be exploited to cause a
stack-based buffer overflow via an overly long (greater than 260
bytes) string passed as argument to the said method.

Successful exploitation allows execution of arbitrary code when a
user visits a malicious website.

The vulnerability is confirmed in version 6.36. Other versions may
also be affected.

SOLUTION:
Set the kill-bit for the affected ActiveX control.
