QID 671107: EulerOS Security Update for ed (EulerOS-SA-2019-2572)

Ed is a line-oriented text editor, used to create, display, and modify text files (both interactively and via shell scripts).
For most purposes, ed has been replaced in normal usage by full-screen editors (emacs and vi, for example).
Ed was the original unix editor, and may be used by some programs.
In general, however, you probably don't need to install it and you probably won't use it.
Security fix(es): regex.c in gnu ed before 1.14.1 allows attackers to cause a denial of service (crash) via a malformed command, which triggers an invalid free.(cve-2017-5357)
