Integer overflow in matroskademux element in gst_matroska_demux_add_wvpk_header function which allows a heap overwrite while parsing matroska files. Potential for arbitrary code execution through heap overwrite.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
