Description:
shinnai has discovered some vulnerabilities in Chilkat XML ActiveX Component, which can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to the ChilkatUtil.CkData.1 (ChilkatUtil.dll) ActiveX control including the insecure "SaveToFile()" and "AppendBinary()" methods. These can be exploited to create arbitrary files or append data to arbitrary files on the system in the context of the currently logged-on user.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are confirmed in ChilkatUtil.dll version 3.0.3.0. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX controls.
