DESCRIPTION:
Multiple vulnerabilities have been discovered in Newv SmartClient
NewvCommon ActiveX control, which can be exploited by malicious
people to manipulate certain data and compromise a user's system.

1) The unsafe method "DelFile()" allows deleting arbitrary files.

2) The unsafe method "RunCommand()" allows executing arbitrary files.


3) A boundary error when processing the "WriteTextFile()" method can
be exploited to cause a stack-based buffer overflow via an overly
long string passed as the "FilePath" parameter.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are confirmed in version 1.1.0.0 (NewvCommon.ocx
1.0.0.18). Other versions may also be affected.

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