CVE-2019-8355 is fixed in 9 products on 1 platform, first by libsox-fmt-all 14.4.2-3ubuntu0.18.04.1, released February 14, 2019. It is not reported as exploited. Patch Radar priority: Routine.
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.
