Fixed In Version:	sudo-1.9.13	Doc Type:	If docs needed, set a value
Doc Text:	A flaw was found in the sudo package, shipped with Red Hat Enterprise Linux 8 and 9, where the "sudoreplay -l' command improperly escapes terminal control characters. As sudo's log messages may contain user-controlled strings, this could allow an attacker to inject terminal control commands, leading to a leak of restricted information.	Story Points:	---
