How to fix?

Upgrade Debian:8 openjdk-7 to version 7u79-2.5.6-1~deb8u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openjdk-7 package and not the openjdk-7 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
