An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-24977 and fix it if it is affected.\n\nWhat it is: CVE-2020-24977 is a medium-severity memory corruption vulnerability in Debian Debian Linux, published on 3 Sep 2020. 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-2020-24977 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-2020-24977/ (Markdown: https://insights.sbomify.com/CVE-2020-24977/index.md)","id":"CVE-2020-24977","markdown":"https://insights.sbomify.com/CVE-2020-24977/index.md","name":"CVE-2020-24977","record":{"aliases":["ALPINE-CVE-2020-24977","DEBIAN-CVE-2020-24977","ECHO-8205-149e-9651","GHSA-w4m9-3rvp-7fhj","JLSEC-2025-69","MGASA-2021-0002","RHSA-2021:1597","RLSA-2021:1597","SUSE-SU-2020:2612-1","UBUNTU-CVE-2020-24977","openSUSE-SU-2020:1430-1","openSUSE-SU-2020:1465-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"libxml2 library","requires_auth":"none","summary":"A global buffer over-read in libxml2 allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"clustered_data_ontap","vendor":"netapp"},{"product":"clustered_data_ontap_antivirus_connector","vendor":"netapp"},{"product":"hci_h410c_firmware","vendor":"netapp"},{"product":"inventory_collect_tool","vendor":"netapp"},{"product":"manageability_software_development_kit","vendor":"netapp"},{"product":"snapdrive","vendor":"netapp"},{"product":"leap","vendor":"opensuse"},{"product":"communications_cloud_native_core_network_function_cloud_native_environment","vendor":"oracle"},{"product":"enterprise_manager_base_platform","vendor":"oracle"},{"product":"enterprise_manager_ops_center","vendor":"oracle"},{"product":"http_server","vendor":"oracle"},{"product":"mysql_workbench","vendor":"oracle"},{"product":"peoplesoft_enterprise_peopletools","vendor":"oracle"},{"product":"real_user_experience_insight","vendor":"oracle"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"GNOME project libxml2 v2.9.10 has a global buffer over-read vulnerability in xmlEncodeEntitiesInternal at libxml2/entities.c.
