An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2012-2871 in the wild and no public exploit code.\n\nAffected product: Apple Iphone Os. 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-2012-2871/ (Markdown: https://insights.sbomify.com/CVE-2012-2871/index.md)","id":"CVE-2012-2871","markdown":"https://insights.sbomify.com/CVE-2012-2871/index.md","name":"CVE-2012-2871","record":{"aliases":["DEBIAN-CVE-2012-2871","GHSA-259f-5jp2-pgmr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","other"],"network_reachable":"yes","non_default_config":false,"product_category":"XML processing library","requires_auth":"none","summary":"Remote attackers can cause denial of service or other impacts via crafted documents due to improper casting in libxml2 XSL transforms.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"iphone_os","vendor":"apple"},{"product":"chrome","vendor":"google"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[],"description":"libxml2 2.9.0-rc1 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly support a cast of an unspecified variable during handling of XSL transforms, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted document, related to the _xmlNs data structure in include/libxml/tree.h.","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-2012-2871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:iphone_os","products":["apple:iphone_os","google:chrome","xmlsoft:libxml2"],"type":"memory_corruption","year":"2012"},"n_packages":0,"n_references":15,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2012-2872"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-2870"},"products":["n/a"],"published":"2012-08-31","related":[{"cvss_score":8.8,"headline":"Apple iOS WebKit Buffer Overflow","id":"CVE-2021-30666","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Memory Corruption","id":"CVE-2021-30761","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Use-After-Free","id":"CVE-2021-30762","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS Webkit Memory Corruption","id":"CVE-2016-4657","kev_date_added":"2022-05-24","published":"2016-08-25"},{"cvss_score":7.8,"headline":"Apple Multiple Products Memory Corruption","id":"CVE-2019-7286","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple iOS Memory Corruption","id":"CVE-2019-7287","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple Multiple Products Use-After-Free","id":"CVE-2019-8605","kev_date_added":"2022-06-27","published":"2019-12-18"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service or other impacts via crafted documents due to improper casting in libxml2 XSL transforms.","url":"https://insights.sbomify.com/CVE-2012-2871/"}
