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-2008-1949 in the wild and no public exploit code.\n\nAffected product: Gnu Gnutls. 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-2008-1949/ (Markdown: https://insights.sbomify.com/CVE-2008-1949/index.md)","id":"CVE-2008-1949","markdown":"https://insights.sbomify.com/CVE-2008-1949/index.md","name":"CVE-2008-1949","record":{"aliases":["GHSA-5mrf-xh4h-r8wx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GnuTLS library","requires_auth":"none","summary":"Remote attackers can cause a denial of service via NULL dereference by sending multiple Client Hello messages in a single TLS packet.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"gnutls","vendor":"gnu"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The _gnutls_recv_client_kx_message function in lib/gnutls_kx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, which allows remote attackers to cause a denial of service (NULL dereference and crash) via a TLS message containing multiple Client Hello messages, aka GNUTLS-SA-2008-1-2.","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-2008-1949","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:gnutls","products":["gnu:gnutls"],"type":"null_dereference","year":"2008"},"n_packages":0,"n_references":40,"next":{"headline":"Integer overflow in n/a","id":"CVE-2008-1950"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2008-1948"},"products":["n/a"],"published":"2008-05-21","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-1948","kev_date_added":null,"published":"2008-05-21"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-5334","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-5336","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-5337","kev_date_added":null,"published":"2017-03-24"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2004-2531","kev_date_added":null,"published":"2005-10-25"},{"cvss_score":7.6,"headline":"Use after free in n/a","id":"CVE-2008-2377","kev_date_added":null,"published":"2008-08-08"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via NULL dereference by sending multiple Client Hello messages in a single TLS packet.","url":"https://insights.sbomify.com/CVE-2008-1949/"}
