Upgrade Ubuntu:14.04 sox to version 14.4.1-3ubuntu1.1+esm1 or higher.
NVD Description

See How to fix? for Ubuntu:14.04 relevant fixed versions and status.
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.
