CVE-2017-18207 (GCVE-0-2017-18207)

Vulnerability from cvelistv5 – Published: 2018-03-01 05:00 – Updated: 2024-08-05 21:13 Disputed

Summary

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.
