CVE-2019-8355

Description

An issue was discovered in SoX 14.4.2. In xmalloc.h, there is an integer overflow on the result of multiplication fed into the lsx_valloc macro that wraps malloc. When the buffer is allocated, it is smaller than expected, leading to a heap-based buffer overflow in channels_start in remix.c.
