CVE-2015-4736
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnspecified vulnerability in Oracle Java SE 7u80 and 8u45 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Deployment.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedJava 7: upgrade to 7u80 or later; Java 8: upgrade to 8u45 or later (or migrate to Java 11/17 LTS for long-term support)
- 1. Identify all systems running Java JDK or JRE versions 1.7.0 or 1.8.0
- 2. For Java 7 users: Download and install Java SE 7u80 or later from Oracle's Java Archive (https://www.oracle.com/java/technologies/java-se-7u80-relnotes.html)
- 3. For Java 8 users: Download and install Java SE 8u45 or later from Oracle's official download page
- 4. Update JAVA_HOME environment variable to point to the newly installed Java path
- 5. Verify the installation by running `java -version` in a command prompt
- 6. Restart any applications or services that rely on the Java runtime to ensure they use the patched version
- 7. Confirm the vulnerability is resolved by checking that the version reported matches 7u80+ or 8u45+

- A config change or rule that shut the vector down
- A gotcha in the upgrade path that cost you an afternoon
