An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-39615 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-2023-39615/ (Markdown: https://insights.sbomify.com/CVE-2023-39615/index.md)","id":"CVE-2023-39615","markdown":"https://insights.sbomify.com/CVE-2023-39615/index.md","name":"CVE-2023-39615","record":{"aliases":["ALSA-2023:7747","ALSA-2024:0119","DEBIAN-CVE-2023-39615","ECHO-b629-387c-838e","GHSA-9fj4-8443-vg2m","JLSEC-2025-81","MGASA-2023-0279","RHSA-2023:7544","RHSA-2023:7747","RHSA-2024:0119","RLSA-2024:0119","SUSE-SU-2023:3666-1","SUSE-SU-2023:3666-2","SUSE-SU-2023:3698-1","SUSE-SU-2023:3699-1","openSUSE-SU-2024:13192-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"Attackers can cause a denial of service in Libxml2 by supplying a crafted XML file, affecting applications using the library.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c.
