Some vulnerabilities have been discovered in Yahoo! Music Jukebox, which can be exploited by malicious people to compromise a user's system.

1) A boundary error in the YMP DataGrid ActiveX control (datagrid.dll) when handling arguments passed to the "AddImage()" and "AddButton()" methods can be exploited to cause a stack-based buffer overflow via an overly long argument.

2) A boundary error in the Yahoo! Mediagrid ActiveX control (mediagridax.dll) when handling arguments passed to the "AddBitmap()" method can be exploited to cause a stack-based buffer overflow via an overly long argument.

Successful exploitation allows execution of arbitrary code when a user e.g. visits a malicious website.

NOTE: Working exploit code is publicly available.

The vulnerabilities are confirmed in Yahoo! Music Jukebox version 2.2.2.056. Other versions may also be affected.
