It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-25683 in the wild and no public exploit code.\n\nAffected product: Canonical apport. 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-2021-25683/ (Markdown: https://insights.sbomify.com/CVE-2021-25683/index.md)","id":"CVE-2021-25683","markdown":"https://insights.sbomify.com/CVE-2021-25683/index.md","name":"CVE-2021-25683","record":{"aliases":["GHSA-v5cq-cqrx-4rpr","UBUNTU-CVE-2021-25683"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ubuntu apport tool","requires_auth":"low_privilege","summary":"Improper parsing of /proc/pid/stat in apport can lead to denial of service, affecting Ubuntu systems.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"apport","vendor":"canonical"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"It was discovered that the get_starttime() function in data/apport did not properly parse the /proc/pid/stat file from the kernel.","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":"apport improperly parses /proc/pid/stat","id":"CVE-2021-25683","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"apport can be stalled by reading a FIFO","id":"CVE-2021-25684"},"packages":[],"prev":{"headline":"apport improperly parses /proc/pid/status","id":"CVE-2021-25682"},"products":["apport"],"published":"2021-06-11","related":[{"cvss_score":8.8,"headline":"apport improperly parses /proc/pid/status","id":"CVE-2021-25682","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":8.8,"headline":"apport can be stalled by reading a FIFO","id":"CVE-2021-25684","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":7.8,"headline":"Race condition in Apport","id":"CVE-2021-3899","kev_date_added":null,"published":"2024-06-03"},{"cvss_score":7.8,"headline":"Other in Apport","id":"CVE-2022-1242","kev_date_added":null,"published":"2024-06-03"},{"cvss_score":7.7,"headline":"local privilege escalation in apport-cli","id":"CVE-2023-1326","kev_date_added":null,"published":"2023-04-13"},{"cvss_score":7.5,"headline":"Denial of service in Apport","id":"CVE-2022-28653","kev_date_added":null,"published":"2025-01-31"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["Canonical"]},"summary":"Improper parsing of /proc/pid/stat in apport can lead to denial of service, affecting Ubuntu systems.","url":"https://insights.sbomify.com/CVE-2021-25683/"}
