[Bug 2064685] Re: write says write: effective gid does not match group of /dev/pts/5
This does not really fix security because one aspect of security is availability to legitimate users and this breaks the latter. Seems there are better ways to fix such as restricting what this can write to with apparmor? Or just fixing the coding so it does parse the input more carefully. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064685 Title: write says write: effective gid does not match group of /dev/pts/5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/2064685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Robert, I believe this is intentional. If you wish to restore the previous behavior, it should be sufficient to change /usr/bin/write.ul to root:tty 02755.
