How to fix?

Upgrade Debian:8 mercurial to version 3.1.2-2+deb8u5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mercurial package and not the mercurial package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The mpatch_decode function in mpatch.c in Mercurial before 4.6.1 mishandles certain situations where there should be at least 12 bytes remaining after the current position in the patch data, but actually are not, aka OVE-20180430-0001.
