Hi,

The following vulnerability was published for sox.

CVE-2019-13590[0]:
| An issue was discovered in libsox.a in SoX 14.4.2. In sox-fmt.h
| (startread function), there is an integer overflow on the result of
| integer addition (wraparound to 0) fed into the lsx_calloc macro that
| wraps malloc. When a NULL pointer is returned, it is used without a
| prior check that it is a valid pointer, leading to a NULL pointer
| dereference on lsx_readbuf in formats_i.c.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
