DESCRIPTION:
Secunia Research has discovered multiple vulnerabilities in SigPlus
Pro ActiveX control, which can be exploited by malicious people to
compromise a user's system.

1) A boundary error when processing the "KeyString" property can be
exploited to cause a heap-based buffer overflow via an overly long
string.

2) A boundary error when processing the "SetLocalIniFilePath()"
method can be exploited to cause a heap-based buffer overflow via an
overly long string passed in the "NewPath" parameter.

3) An error due to an unsafe "SetLogFilePath()" method creating a log
file in a specified location can be exploited in combination with e.g.
the "SigMessage()" method to create an arbitrary file with controlled
content.

4) A boundary error when processing the "SetTabletPortPath()" method
can be exploited to cause a heap-based buffer overflow via an overly
long string passed in the "NewPortPath" parameter.

Successful exploitation of these vulnerabilities allows execution of
arbitrary code.

The vulnerabilities are confirmed in version 3.95. Other versions may
also be affected.

SOLUTION:
Upgrade to version 4.29.
