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-2019-11577 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-2019-11577/ (Markdown: https://insights.sbomify.com/CVE-2019-11577/index.md)","id":"CVE-2019-11577","markdown":"https://insights.sbomify.com/CVE-2019-11577/index.md","name":"CVE-2019-11577","record":{"aliases":["DEBIAN-CVE-2019-11577","GHSA-2ppc-97gw-v7r8"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"dhcpcd DHCP client","requires_auth":"none","summary":"A buffer overflow in dhcpcd allows attackers to execute arbitrary code or cause denial of service via crafted DHCPv6 messages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dhcpcd","vendor":"dhcpcd_project"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"dhcpcd before 7.2.1 contains a buffer overflow in dhcp6_findna in dhcp6.c when reading NA/TA addresses.","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":"Memory corruption in n/a","id":"CVE-2019-11577","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2019"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2019-11578"},"packages":[],"prev":{"headline":"Gitea Allows 1FA Even for 2FA-Enrolled Accounts","id":"CVE-2019-11576"},"products":["n/a"],"published":"2019-04-28","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-1503","kev_date_added":null,"published":"2016-04-18"},{"cvss_score":7.5,"headline":"dhcpcd before 6.10.0 allows remote attackers to cause a denial of service (invalid read and crash) via vectors related to the option length.","id":"CVE-2016-1504","kev_date_added":null,"published":"2017-02-07"},{"cvss_score":7.1,"headline":"dhcpcd Memory Leak DoS via IPv6 Router Advertisement Handling","id":"CVE-2026-56116","kev_date_added":null,"published":"2026-06-23"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2014-7912","kev_date_added":null,"published":"2015-07-30"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2014-7913","kev_date_added":null,"published":"2015-07-30"},{"cvss_score":6,"headline":"dhcpcd Heap Use-After-Free in dhcp6_deprecateaddrs via DHCPv6 RENEW","id":"CVE-2026-56113","kev_date_added":null,"published":"2026-06-23"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"A buffer overflow in dhcpcd allows attackers to execute arbitrary code or cause denial of service via crafted DHCPv6 messages.","url":"https://insights.sbomify.com/CVE-2019-11577/"}
