    Debian Bug     : 950371
    
    Joe Vennix discovered a stack-based buffer overflow vulnerability in
    sudo, a program designed to provide limited super user privileges to
    specific users, triggerable when configured with the "pwfeedback" option
    enabled. An unprivileged user can take advantage of this flaw to obtain
    full root privileges.
    
    Details can be found in the upstream advisory at
    https://www.sudo.ws/alerts/pwfeedback.html .
    
    For the oldstable distribution (stretch), this problem has been fixed
    in version 1.8.19p1-2.1+deb9u2.
    
    For the stable distribution (buster), exploitation of the bug is
    prevented due to a change in EOF handling introduced in 1.8.26.
    
    We recommend that you upgrade your sudo packages.
    
    For the detailed security status of sudo please refer to its security
    tracker page at:
