SOGo does not validate the signatures of any SAML assertions it receives. Any actor with network access to the deployment could impersonate users when SAML is the authentication method.

For Debian 9 stretch, this problem has been fixed in version 3.2.6-2+deb9u1.

We recommend that you upgrade your sogo packages.

ATTENTION! If you are using SAML authentication, use sogo-tool to immediately delete users sessions and force all users to visit the login page:

sogo-tool -v expire-sessions 1

systemctl restart memcached

For the detailed security status of sogo please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
