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-2021-44758 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-44758/ (Markdown: https://insights.sbomify.com/CVE-2021-44758/index.md)","id":"CVE-2021-44758","markdown":"https://insights.sbomify.com/CVE-2021-44758/index.md","name":"CVE-2021-44758","record":{"aliases":["ALPINE-CVE-2021-44758","AZL-44859","CLEANSTART-2024-UF28552","DEBIAN-CVE-2021-44758","GHSA-69h9-669w-88xv","UBUNTU-CVE-2021-44758"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Heimdal Kerberos library","requires_auth":"none","summary":"Attackers can cause a denial of service in Heimdal via a NULL pointer dereference in the SPNEGO acceptor mechanism.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"heimdal","vendor":"heimdal_project"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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":"Heimdal before 7.7.1 allows attackers to cause a NULL pointer dereference in a SPNEGO acceptor via a preferred_mech_type of GSS_C_NO_OID and a nonzero initial_response value to send_accept.","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":"Null dereference in n/a","id":"CVE-2021-44758","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Improper authentication vulnerability in TLS origin verification","id":"CVE-2021-44759"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-44757"},"products":["n/a"],"published":"2022-12-26","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-44640","kev_date_added":null,"published":"2022-12-25"},{"cvss_score":8.8,"headline":"Integer overflow in n/a","id":"CVE-2022-42898","kev_date_added":null,"published":"2022-12-25"},{"cvss_score":7.5,"headline":"Null dereference in Heimdal Software Kerberos","id":"CVE-2022-3116","kev_date_added":null,"published":"2023-03-27"},{"cvss_score":7.5,"headline":"Security feature bypass in Samba","id":"CVE-2022-45142","kev_date_added":null,"published":"2023-03-06"},{"cvss_score":7.5,"headline":"Auth bypass in samba","id":"CVE-2018-16860","kev_date_added":null,"published":"2019-07-31"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2017-6594","kev_date_added":null,"published":"2017-08-28"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-14","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in Heimdal via a NULL pointer dereference in the SPNEGO acceptor mechanism.","url":"https://insights.sbomify.com/CVE-2021-44758/"}
