CVE ID         : CVE-2022-45939

It was discovered that there was an issue in Emacs where where
attackers could have executed arbitrary commands via shell
metacharacters in the name of a source-code file.

when calling the (external) ctags(1) binary.

For Debian 10 buster, this problem has been fixed in version
1:26.1+1-3.2+deb10u3.
