CVE-2018-20406

Priority
Description
Modules/_pickle.c in Python before 3.7.1 has an integer overflow via a
large LONG_BINPUT value that is mishandled during a "resize to twice the
size" attempt. This issue might cause memory exhaustion, but is only
relevant if the pickle format is used for serializing tens or hundreds of
gigabytes of data.
