While pwfeedback is not enabled by + default in the upstream version of sudo, some systems, such as + Linux Mint and Elementary OS, do enable it in their default + sudoers files.</p> + <p>Due to a bug, when the pwfeedback option is enabled in the + sudoers file, a user may be able to trigger a stack-based buffer + overflow.
