shinnai has discovered a vulnerability in ebCrypt, which can be exploited by malicious people to overwrite arbitrary files.
The vulnerability is caused due to the EbCrypt.eb_c_PRNGenerator.1 ActiveX control (ebCrypt.dll) including the insecure "SaveToFile()" method, which saves a file specified as an argument. This can be exploited to overwrite and corrupt arbitrary files on the system.
The vulnerability is confirmed in version 188.8.131.527. Other versions may also be affected.
