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-2011-1944 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-2011-1944/ (Markdown: https://insights.sbomify.com/CVE-2011-1944/index.md)","id":"CVE-2011-1944","markdown":"https://insights.sbomify.com/CVE-2011-1944/index.md","name":"CVE-2011-1944","record":{"aliases":["DEBIAN-CVE-2011-1944","DSA-2255-1","GHSA-447f-hj4w-5xch"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"Integer overflow in libxml2 allows attackers to cause denial of service or execute arbitrary code via crafted XML files.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libxml","vendor":"xmlsoft"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Integer overflow in xpath.c in libxml2 2.6.x through 2.6.32 and 2.7.x through 2.7.8, and libxml 1.8.16 and earlier, allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted XML file that triggers a heap-based buffer overflow when adding a new namespace node, related to handling of XPath expressions.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-05-31","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-05-31","kind":"exploitdb","ref":"35810","stars":null,"title":"libxmlInvalid 2.7.x - XPath Multiple Memory Corruption Vulnerabilities"}],"tier":"weaponised"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2011-1944","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xmlsoft:libxml2","products":["xmlsoft:libxml2"],"type":"integer_overflow","year":"2011"},"n_packages":0,"n_references":21,"next":{"headline":"Weak cryptography in n/a","id":"CVE-2011-1945"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2011-1943"},"products":["n/a"],"published":"2011-09-02","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2008-4226","kev_date_added":null,"published":"2008-11-25"},{"cvss_score":7.8,"headline":"Integer overflow in n/a","id":"CVE-2008-4225","kev_date_added":null,"published":"2008-11-25"},{"cvss_score":4.3,"headline":"Denial of service in n/a","id":"CVE-2009-2414","kev_date_added":null,"published":"2009-08-11"}],"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":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Integer overflow in libxml2 allows attackers to cause denial of service or execute arbitrary code via crafted XML files.","url":"https://insights.sbomify.com/CVE-2011-1944/"}
