Summary

Several local side channel attacks and a denial of service via large
Diffie-Hellman parameters were discovered in OpenSSL, a Secure Sockets
Layer toolkit.

For the stable distribution (stretch), these problems have been fixed in
version 1.0.2q-1~deb9u1. Going forward, openssl1.0 security updates for
stretch will be based on the 1.0.2x upstream releases.

We recommend that you upgrade your openssl1.0 packages.

For the detailed security status of openssl1.0 please refer to
