[Bug 223159] New: chsh allows to change login shell even if the user has a restricted shell
https://bugzilla.novell.com/show_bug.cgi?id=223159 Summary: chsh allows to change login shell even if the user has a restricted shell Product: SUSE Linux 10.1 Version: Final Platform: Other OS/Version: SuSE Linux 10.1 Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: kukuk@novell.com ReportedBy: lmuelle@novell.com QAContact: qa@suse.de CC: kj@sernet.de lmuelle@lisa:~> LC_ALL=POSIX chsh Changing login shell for lmuelle. Password: Enter the new value, or press return for the default. Login Shell [/usr/bin/rbash]: /bin/bash Shell changed. But the chsh man page states: An account with a restricted login shell may not change their login shell. Is there a different restricted login shell meant by the man page? Do I have to edit /etc/shells on all systems where I'd like to lock the users to rbash? This might even be appraised as a security problem. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

The user calls the support. The support department call the support developemnt interface team. This team calls the maintainer of the pwdutils. The alternative is to remove /usr/bin/rbash from /etc/shells. For those customers with modifies /etc/shells the %config in the files section ensures to create a backup. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
