Stack-based buffer overflow in the GetUiDllVersion function in an ActiveX control in UiCheck.dll before 1.0.0.7 in UiTV UiPlayer, as used in BaiduX and other products, allows remote attackers to execute arbitrary code via the filename parameter.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
