Log4JShell ByteCode Detector
To check if your jar file is affected by the critical CVE-2021-44228, we provide an open-source command line tool https://github.com/CodeShield-Security/Log4JShell-Bytecode-Detector. The tool scans the jar file and compares the classses against a set of pre-computed hashes of the vulnerable Log4j classes. Since our tool only uses the hash and fingerprints of bytecode classes, no source code needs to be available.

Just Say No To `:Latest`
Hadolint is great! If you want to customize your lint logic beyond the checks in it, I recently wrote a Semgrep rule to require all our Dockerfiles to pin images with a sha256 hash that could be a good starting point: https://github.com/returntocorp/semgrep-rules/pull/1861/file...
