What Changed
Several security issues were fixed in Go Networking. In general, a standard system update will make all the necessary changes.
What To Validate Now
- Inventory. Locate golang-golang-x-net on Ubuntu 22.04 LTS (jammy); record versions, enabled features, exposure paths, owners, dependencies, support channels, and maintenance groups.
- Establish applicability. Compare every deployment with the authority's affected statement: The Ubuntu 22.04 LTS golang-golang-x-net packages enumerated by USN-8900-1. Do not infer applicability from product family, CVSS, or Internet reachability alone.
- Remediate. Apply jammy: golang-golang-x-net 1:0.0+git20211209.491a49a+dfsg-1ubuntu0.1 through the authority-supported channel and follow the current advisory.
- Validate. Confirm the resulting Go Networking libraries build or managed state, exercise representative services and recovery paths, monitor for regressions, and retain the result.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Use the Ubuntu jammy security pocket, then rebuild or restart Go applications that vendor or dynamically consume the affected library where operationally applicable. Preserve pre-change state, installation output, logs, validation evidence, and rollback decisions.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
