What Changed
Several security issues were fixed in libsoup. In general, a standard system update will make all the necessary changes.
What To Validate Now
- Inventory. Locate libsoup on Ubuntu 26.04 (resolute) LTS, Ubuntu 24.04 (noble) LTS, Ubuntu 22.04 (jammy) LTS, Ubuntu 20.04 (focal) ESM, Ubuntu 18.04 (bionic) ESM, Ubuntu 16.04 (xenial) ESM; 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 releases and source packages enumerated in USN-8890-1: Ubuntu 26.04 (resolute) LTS, Ubuntu 24.04 (noble) LTS, Ubuntu 22.04 (jammy) LTS, Ubuntu 20.04 (focal) ESM, Ubuntu 18.04 (bionic) ESM, Ubuntu 16.04 (xenial) ESM. Do not infer applicability from product family, CVSS, or Internet reachability alone.
- Remediate. Apply bionic: libsoup2.4 2.62.1-1ubuntu0.4+esm9 / focal: libsoup2.4 2.70.0-1ubuntu0.5+esm4 / jammy: libsoup2.4 2.74.2-3ubuntu0.9 / jammy: libsoup3 3.0.7-0ubuntu1+esm9 / noble: libsoup2.4 2.74.3-6ubuntu1.9 / noble: libsoup3 3.4.4-5ubuntu0.9 / resolute: libsoup2.4 2.74.3-10.1ubuntu5+esm3 / resolute: libsoup3 3.6.6-1ubuntu0.1 / xenial: libsoup2.4 2.52.2-1ubuntu0.3+esm8 through the authority-supported channel and follow the current advisory.
- Validate. Confirm the resulting libsoup 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 matching Ubuntu security or ESM pocket and validate dependent applications after updating. 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.
