No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/ALEA-2021-5239/ (Markdown: https://insights.sbomify.com/ALEA-2021-5239/index.md)","id":"ALEA-2021:5239","markdown":"https://insights.sbomify.com/ALEA-2021-5239/index.md","name":"ALEA-2021:5239","record":{"aliases":[],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"Cloud initialization tool","requires_auth":"unknown","summary":"Cloud-init fails to start or configure routes correctly after updates, potentially causing service disruption for cloud instances.","user_interaction":"unknown","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The cloud-init packages provide a set of init scripts for cloud instances.\nCloud instances need special scripts to run during initialization to\nretrieve and install SSH keys, and to let the user run various scripts.\n\nBug Fix(es) and Enhancement(s):\n\n* cloud-init.service fails to start after package update (BZ#2028738)\n\n* [AlmaLinux-8] Above 19.2 of cloud-init fails to configure routes when\nconfiguring static and default routes to the same destination IP\n(BZ#2028756)","ecosystems":["AlmaLinux:8"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"cloud-init bug fix and enhancement update","id":"ALEA-2021:5239","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"AlmaLinux:8","fixed":["21.1-7.el8_5.3.alma"],"introduced":["0"],"last_affected":[],"package":"cloud-init","purl":"pkg:rpm/almalinux/cloud-init","source":"ALEA-2021:5239"}],"products":null,"published":"2021-12-21","related":[],"sources":[{"class":"attribution","licence":"MIT","name":"AlmaLinux","prefix":"ALEA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Cloud-init fails to start or configure routes correctly after updates, potentially causing service disruption for cloud instances.","url":"https://insights.sbomify.com/ALEA-2021-5239/"}
