An issue was discovered in SoX 14.4.2. lsx_make_lpf in effect_i_dsp.c has an integer overflow on the result of multiplication fed into malloc. When the buffer is allocated, it is smaller than expected, leading to a heap-based buffer overflow.
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.
