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_apply function in mpatch.c in Mercurial before 4.6.1 incorrectly proceeds in cases where the fragment start is past the end of the original data, aka OVE-20180430-0004.
