Parvez Anwar has discovered two vulnerabilities in InterVideo Home Theater, which can be exploited by malicious people to compromise a user's system.
1) A boundary error within the WinDVDX ActiveX control when handling the "GetDiscType()" method can be exploited to cause a stack-based buffer overflow by passing an overly long string (greater than 250 bytes) as argument to the affected method.
2) A boundary error within the WinDVDX ActiveX control when handling the "AddFileList()" method can be exploited to cause a heap-based buffer overflow by passing an overly long string as argument to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerabilities are reported in version 220.127.116.11 and confirmed in version 18.104.22.168 incorporating WinDVDX.ocx version 22.214.171.124. Other versions may also be affected.
Solution: Set the kill-bit on the affected ActiveX control.
