NVD Description

Note: Versions mentioned in the description apply only to the upstream patch package and not the patch package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character. NOTE: this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated to a shell metacharacter.
