It certainly looks like it.

Use visudo to comment out or remove that line.

Corona is right (do NOT edit "/etc/sudoers" directly, always use "visudo"), but the real question is not "how to remove these rights", but "how did he get them in first place?"

A user having this kind of "free pass for all" - even more so individually and not via a group - looks like a severe security breach to an outsider like me. You should take away the rights but also investigate how it was possible to get them in first place - and shut down this possibility immediately.

Just my 2 cents.
