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.
GNU patch through 2.7.6 is vulnerable to OS shell command injection that can be exploited by opening a crafted patch file that contains an ed style diff payload with shell metacharacters. The ed editor does not need to be present on the vulnerable system. This is different from CVE-2018-1000156.
