Debian: DSA-4446-1 Critical: Lemonldap-NG Session Token Issue

It was discovered that the Lemonldap::NG web SSO system performed
insuffient validation of session tokens if the "tokenUseGlobalStorage"
option is enabled, which could grant users with access to the main
session database access to an anonymous session.

For the stable distribution (stretch), this problem has been fixed in
version 1.9.7-3+deb9u1.

We recommend that you upgrade your lemonldap-ng packages.
