fix(cassandra): refresh vulnerable runtime dependencies - #1611
Conversation
Upgrade OpenSSL to at least 3.5.7-1~deb13u2, Jackson to 2.21.4, and Netty to 4.1.136.Final. Keep the downloaded Java artifacts locked to their Maven Central SHA-256 checksums. Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

Full details: Linked Issues checkExplanation The changes add exporter Netty repackaging, but they do not show the required OpenSSL, Jackson, or Cassandra server Netty updates from issue Resolution Implement or provide evidence for the required Cassandra runtime dependency updates, including OpenSSL, Jackson, and server-side Netty. Confirm both supported architectures and preserve startup, configuration initialization, and chart compatibility. Full details: Out of Scope Changes checkExplanation The exporter JAR repackaging is outside the linked issue's stated scope, which targets Cassandra server runtime dependencies.

Fail when exporter POM metadata is absent.
If META-INF/maven/com.zegelin.cassandra-exporter is absent, find fails but the trailing while returns success. The script then creates an archive without updating exporter POM metadata. Validate the directory and require at least one pom.xml before the pipeline.

site:docs.oracle.com Java JAR verification modified signed JAR entry SecurityException class loading
💡 Result:
In Java, when a signed JAR entry is modified after being signed, it violates the integrity verification process, leading to a SecurityException [1][2]. The Java runtime verification process ensures that the contents of a JAR file have not changed since it was signed [3][4]. When a JAR entry (such as a class file) is read from a signed JAR, the Java environment performs the following integrity checks [3][4]: 1. Digest Calculation: The runtime computes the digest (hash) of the actual file data currently in the JAR [4][5]. 2. Comparison: It compares this computed digest against the digest stored in the JAR's manifest file [4][6]. 3. Manifest Verification: It further verifies the manifest against the signature file (.SF), which is itself validated by a signature block file (.DSA,.RSA, or.EC) [3][7][5]. If the file data has been modified, the computed digest will not match the one recorded in the manifest [4][5]. When this mismatch is detected during class loading or any other access to the entry's input stream, the Java runtime throws a SecurityException [1][8][4]. Specific technical behaviors include: - Verification Timing: Verification typically occurs when the entry is read from the JAR's input stream (e.g., via JarInputStream) [1][2]. Once an entry is completely read and verified, its code signers or certificates can be retrieved [1][9]. - Scope: This mechanism applies to all entries covered by the signature, ensuring that tampering with any class file or resource file within the signed JAR triggers the security failure [3][4]. - Exception Trigger: The SecurityException is a runtime mechanism to prevent the loading or execution of code that has been altered, thereby protecting the system from potentially malicious or corrupt code [4][10]. If you are encountering this exception, it indicates that the file integrity has been compromised either through direct modification of the JAR file contents, corruption of the file, or an incorrect signing process [4][10].

Remove or reject invalidated JAR signatures.
If the input exporter JAR contains signature files, the script preserves them while replacing signed Netty entries. Java can then throw SecurityException when the agent loads a modified entry. Strip the signature files or reject signed input JARs. Add a signed-input regression test.

TL;DR
Refresh the Cassandra 5.0.9 runtime's OpenSSL, Jackson, and Netty dependencies to published fixed versions while preserving the Cassandra release and image interface.
Additional Details
Apache Cassandra 5.0.9 remains the latest supported 5.0 release, and the current official image still bundles OpenSSL 3.5.6, Jackson 2.19.2, and Netty 4.1.130.Final. This change therefore:
libssl3t64andopenssl-provider-legacyfrom Debian security repositories, with a build-time floor of3.5.7-1~deb13u2;The exporter agent and its shaded dependencies are intentionally unchanged. They are tracked separately.
Jackson and Netty remain Apache-2.0 dependencies already distributed by Cassandra. The version refresh does not add a new license or require a NOTICE change.
For the Reviewer
Please focus on the dependency lock and replacement layer in
infra/cassandra/Dockerfile. A future Cassandra base-digest update should compare its bundled dependency set againstjava-libraries.lockand remove the overlay once an upstream release includes equivalent or newer fixes.For QA
Local validation completed:
docker build --progress=plain -t nvcf-cassandra:1605 infra/cassandradocker buildx build --progress=plain --platform linux/amd64,linux/arm64 --output type=oci,dest=/private/tmp/nvcf-cassandra-1605.oci infra/cassandraUNQA is recommended for a chart-level rolling-upgrade and TLS-enabled cluster check because the change updates database transport, serialization, and cryptographic runtime libraries.
