Multiple vulnerabilities have been found in the Symfony PHP framework
which could lead to open redirects, cross-site request forgery,
information disclosure, session fixation or denial of service.

For the stable distribution (stretch), these problems have been fixed in
version 2.8.7+dfsg-1.3+deb9u1.

We recommend that you upgrade your symfony packages.
