Immediately following this release, Oracle announced that Java 7 had reached its End of Life (EOL) and would no longer receive public security updates. For security professionals, Update 80 is not a "secure version" of Java 7; it is a frozen snapshot of a platform riddled with known, unpatched vulnerabilities.

Java's security was originally built on a "sandbox" that restricted what untrusted code could do. Over the years, numerous "Sandbox Escapes" have been discovered. In Update 80, many of the APIs related to reflection and libraries like AWT and Swing have known bypasses that allow attackers to break out of the restricted environment.

Attackers would combine multiple vulnerabilities to first gain a foothold on a system and then escalate privileges, move laterally across a network, and install malware, ransomware, or backdoors. Cybercriminal exploit kits, such as the notorious Blackhole and Nuclear Pack, were observed actively using these vulnerabilities on a large scale to infect systems.
