Affected: Ubuntu:Pro:14.04:LTS: sox, Ubuntu:16.04:LTS: sox, Ubuntu:18.04:LTS: sox

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.
