It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-33634 in the wild and no public exploit code.\n\nAffected product: openEuler lcr. 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/CVE-2021-33634/ (Markdown: https://insights.sbomify.com/CVE-2021-33634/index.md)","id":"CVE-2021-33634","markdown":"https://insights.sbomify.com/CVE-2021-33634/index.md","name":"CVE-2021-33634","record":{"aliases":["GHSA-5mrv-f9xf-hpqp","OESA-2023-1692"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"iSulad container runtime","requires_auth":"none","summary":"Malicious container images can cause denial of service in iSulad using the default lcr+lxc runtime, affecting openEuler systems.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openEuler","cpe":[{"product":"icr","vendor":"openeuler"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-665","name":"Improper Initialization"}],"description":"iSulad uses the lcr+lxc runtime (default) to run malicious images, which can cause DOS.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Malicious image running containers may cause DoS attacks","id":"CVE-2021-33634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Pull malicious images may cause process to be hijacked","id":"CVE-2021-33635"},"packages":[],"prev":{"headline":"Command Injection in aops-ceres","id":"CVE-2021-33633"},"products":["lcr"],"published":"2023-10-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-09","vendors":["openEuler"]},"summary":"Malicious container images can cause denial of service in iSulad using the default lcr+lxc runtime, affecting openEuler systems.","url":"https://insights.sbomify.com/CVE-2021-33634/"}
