The affected product’s proprietary protocol CSC allows for calling numerous function codes. In order to call those function codes, the user must supply parameters. There is no sanitation on the value of the offset, which allows the client to specify any offset and read out-of-bounds data.
Solution:
The product reads data past the end, or before the beginning, of the intended buffer.
