An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-34459 and fix it if it is affected.\n\nWhat it is: CVE-2024-34459 is a high-severity memory corruption vulnerability in Xmlsoft Libxml2, published on 13 May 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-34459 exists.\n\nAffected product: Xmlsoft Libxml2. 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-2024-34459/ (Markdown: https://insights.sbomify.com/CVE-2024-34459/index.md)","id":"CVE-2024-34459","markdown":"https://insights.sbomify.com/CVE-2024-34459/index.md","name":"CVE-2024-34459","record":{"aliases":["ALPINE-CVE-2024-34459","ALSA-2026:26354","ALSA-2026:28234","ALSA-2026:28254","AZL-42019","AZL-42027","BELL-CVE-2024-34459","DEBIAN-CVE-2024-34459","ECHO-8b77-066d-6b10","GHSA-vv62-jfwq-693v","JLSEC-2025-84","MGASA-2024-0211","OESA-2024-1641","RHSA-2026:26354","RHSA-2026:27736","RHSA-2026:27737","RHSA-2026:27739","RHSA-2026:28234","RHSA-2026:28254","RHSA-2026:33632","RHSA-2026:33633","RHSA-2026:33634","RHSA-2026:33635","RLSA-2026:26354","RLSA-2026:28234","RLSA-2026:28254","SUSE-SU-2024:2267-1","SUSE-SU-2024:2279-1","SUSE-SU-2024:2288-1","SUSE-SU-2024:2290-1","SUSE-SU-2025:20043-1","UBUNTU-CVE-2024-34459","openSUSE-SU-2024:13971-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libxml2 XML parser","requires_auth":"none","summary":"A buffer over-read in libxml2's xmllint tool can cause a crash when formatting HTML error messages, requiring an upgrade to patched versions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7.
