An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-39028 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2022-39028/ (Markdown: https://insights.sbomify.com/CVE-2022-39028/index.md)","id":"CVE-2022-39028","markdown":"https://insights.sbomify.com/CVE-2022-39028/index.md","name":"CVE-2022-39028","record":{"aliases":["DEBIAN-CVE-2022-39028","GHSA-jq82-jqvw-64w3","MGASA-2022-0394","MGASA-2022-0460","OESA-2024-1354","OESA-2024-1359","OESA-2024-1360","OESA-2024-1361","OESA-2024-1362","OESA-2024-1363","SUSE-SU-2022:3471-1","SUSE-SU-2022:3735-1","SUSE-SU-2022:3783-1","UBUNTU-CVE-2022-39028","openSUSE-SU-2024:12436-1"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Telnet daemon","requires_auth":"none","summary":"A NULL pointer dereference in telnetd allows remote attackers to cause a denial of service by crashing the service repeatedly.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"inetutils","vendor":"gnu"},{"product":"kerberos_5","vendor":"mit"},{"product":"netkit-telnet","vendor":"netkit-telnet_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"telnetd in GNU Inetutils through 2.3, MIT krb5-appl through 1.0.3, and derivative works has a NULL pointer dereference via 0xff 0xf7 or 0xff 0xf8.
