Jeroen Ploemen uploaded new packages for sabnzbdplus which fixed the
following security problem:

In sabnzbdplus <= 5.1.0, an attacker with access to the
password-protected web interface can bypass the authentication and
obtain a valid session without knowing the username or password.

For the trixie-backports distribution the problems have been fixed in
version 5.1.1+dfsg-1~bpo13+1.
