Place the Java 7u80 server in a strict, isolated demilitarized zone (DMZ) or private VLAN. Block all inbound and outbound internet access unless absolutely necessary.
Improved memory management to prevent "Buffer Overflow" attacks.
The most critical takeaway for today is that Java 7 Update 80 is profoundly unsafe for any application exposed to untrusted code or the internet. The risk has evolved in three distinct phases since 2015. java 7 update 80 vulnerabilities
For any organization or individual still running Java 7 Update 80, the only secure option is to migrate away from the platform immediately. The risk of remaining on an unsupported version is no longer theoretical; it is a critical, known vulnerability.

Java 7 Update 80 (7u80), released in April 2015, marks the final public updates offered by Oracle for the Java SE 7 platform. Because it represents the end-of-life (EOL) milestone for public support, any system running this specific version is exposed to all subsequent vulnerabilities discovered in the Java 7 codebase. The most critical takeaway for today is that
While Oracle's April 2015 Critical Patch Update (CPU) addressed several flaws to bring the software to the 7u80 state, hundreds of subsequent CVEs have since accumulated. Below are some of the most critical classes of vulnerabilities inherent to systems marooned on Java 7u80.
— Regularly scan Java 7u80 systems for known CVEs and monitor logs for exploitation attempts.
Vulnerabilities have been identified in the 2D graphics component and library handling that allow remote attackers to gain full control of the Java Virtual Machine (JVM). The Danger of Using Update 80 Today
Any organization still running Java 7u80 should immediately engage with one of these vendors if migration to Java 8/11 is not feasible within a reasonable timeframe.
