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-2017-7376 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-2017-7376/ (Markdown: https://insights.sbomify.com/CVE-2017-7376/index.md)","id":"CVE-2017-7376","markdown":"https://insights.sbomify.com/CVE-2017-7376/index.md","name":"CVE-2017-7376","record":{"aliases":["DEBIAN-CVE-2017-7376","ECHO-c3d9-c09e-39d9","GHSA-j45j-3c7p-vf8f","UBUNTU-CVE-2017-7376"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"libxml2 library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a buffer overflow in libxml2 caused by incorrect port value limits during redirect handling.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"android","vendor":"google"},{"product":"libxml2","vendor":"xmlsoft"}],"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":"Buffer overflow in libxml2 allows remote attackers to execute arbitrary code by leveraging an incorrect limit for port values when handling redirects.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-06-11","github_poc":1,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-06-11T06:55:32Z","kind":"github_poc","ref":"https://github.com/brahmstaedt/libxml2-exploit","stars":3,"title":"An example exploit for CVE-2017-7376"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2017-7376","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"debian:debian_linux","products":["debian:debian_linux","google:android","xmlsoft:libxml2"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":7,"next":{"headline":"Denial of service in n/a","id":"CVE-2017-7377"},"packages":[],"prev":{"headline":"XML external entity in n/a","id":"CVE-2017-7375"},"products":["n/a"],"published":"2018-02-19","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via a buffer overflow in libxml2 caused by incorrect port value limits during redirect handling.","url":"https://insights.sbomify.com/CVE-2017-7376/"}
