Really? If the terminal I last ran sudo in is open still on the machine, and it's unlocked, I couldn't simply change the time back to the previous sudo command an escalate?
Even if it's a remote chance, it's still an easy exploit. /var/log/auth.log is certainly readable by a program that uses a different exploit to gain access to that admin user (say, a browser exploit) and contains the PTY and timestamp. It doesn't even have to be exact: It just has to be ~ 15 minutes after the last sudo, right? This is a simple upgrade that even your parent distribution has adopted for their stable. Why ignore it for over a year? Can you please show me the information about the inode? My impression was that it was based on the SID, rather than inode, but perhaps that has changed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1219337 Title: Users can change the clock without authenticating, allowing them to locally exploit sudo.
