CPython CVE-2018-1000117 Local Buffer Overflow Vulnerability

CPython is prone to a local buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.

Attackers can exploit this issue to execute arbitrary code or cause denial-of-service condition.

CPython 3.2 through 3.6.4 are vulnerable.
