https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238995 Bug ID: 238995 Summary: adduser does not check for pre-existing user field entries in /etc/group Product: Base System Version: 12.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: dclarke@blastwave.org Seems minor but merely annoying. One may edit /etc/group before running adduser and put in the future username for some group. Seems trivial. vesta# uname -a=20 FreeBSD vesta 12.0-RELEASE-p4 FreeBSD 12.0-RELEASE-p4 GENERIC amd64 Toss a group into /etc/group : vesta# /usr/bin/printf "foo:*:12345:someuser\n" >> /etc/group vesta# grep 'foo' /etc/group foo:*:12345:someuser vesta#=20 Now run adduser and toss a new user into the system with that group as a part of the creation process :=20 vesta# adduser Username: someuser Full name: Some Test User Uid (Leave empty for default): 54321 Login group [someuser]:=20 Login group is someuser. Invite someuser into other groups? []: foo Login class [default]:=20 Shell (sh csh tcsh bash rbash git-shell nologin) [sh]:=20 Home directory [/home/someuser]:=20 Home directory permissions (Leave empty for default):=20 Use password-based authentication? [yes]:=20 Use an empty password? (yes/no) [no]:=20 Use a random password? (yes/no) [no]:=20 Enter password:=20 Enter password again:=20 Lock out the account after creation? [no]:=20 Username : someuser Password : ***** Full Name : Some Test User Uid : 54321 Class :=20 Groups : someuser foo Home : /home/someuser Home Mode :=20 Shell : /bin/sh Locked : no OK? (yes/no): yes adduser: INFO: Successfully added (someuser) to the user database. Add another user? (yes/no): no Goodbye! vesta#=20 Here adduser duplicates the entry for the group 'foo' :=20 vesta# grep 'foo' /etc/group foo:*:12345:someuser,someuser vesta#=20 Seems trivial and slightly annoying. --=20 Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken GreyBeard and suspenders optional --=20 You are receiving this mail because: You are the assignee for the bug.=
