Description:
Some vulnerabilities have been discovered in Persits Software XUpload, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to boundary errors in the Persits.XUpload.2 ActiveX control (XUpload.ocx) when processing arguments passed to the "AddFile()" method. This can be exploited to cause stack-based buffer overflows by passing specially crafted, overly-long strings as argument to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are confirmed in version 3.0.0.4 and 2.1.0.1. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
