Description
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.
A flaw was found in GNU patch through version 2.7.6. Strings beginning with a exclamation mark are not blocked by default. When ed receives an exclamation mark-prefixed command line argument, the argument is executed as a shell command. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
