CVE-2017-18207 is a vulnerability of currently unknown severity. The Wave_read._read_fmt_chunk function in Lib/wave.py in Python through 3.6.4 does not ensure a nonzero channel value, which allows attackers to cause a denial of service (divide-by-zero and exception) via a crafted wav format audio file. NOTE: the vendor disputes this issue because Python applications "need to be prepared to handle a wide variety of exceptions.. EPSS estimates a 1.35% chance of exploitation in the next 30 days.
