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-2011-1779 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2011-1779/ (Markdown: https://insights.sbomify.com/CVE-2011-1779/index.md)","id":"CVE-2011-1779","markdown":"https://insights.sbomify.com/CVE-2011-1779/index.md","name":"CVE-2011-1779","record":{"aliases":["DEBIAN-CVE-2011-1779","GHSA-xm97-4p58-pfr9"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"libarchive library","requires_auth":"none","summary":"Remote attackers can cause denial of service or potentially execute code via crafted TAR or ISO9660 archives in libarchive.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"libarchive","vendor":"freebsd"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Multiple use-after-free vulnerabilities in libarchive 2.8.4 and 2.8.5 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted (1) TAR archive or (2) ISO9660 image.","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":"Use after free in n/a","id":"CVE-2011-1779","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2011"},"n_packages":0,"n_references":2,"next":{"headline":"Race condition in n/a","id":"CVE-2011-1780"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-1778"},"products":["n/a"],"published":"2012-04-13","related":[{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2007-3641","kev_date_added":null,"published":"2007-07-14"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2010-4666","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-1777","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-1778","kev_date_added":null,"published":"2012-04-13"},{"cvss_score":4.3,"headline":"Null dereference in n/a","id":"CVE-2007-3645","kev_date_added":null,"published":"2007-07-15"},{"cvss_score":4.3,"headline":"Denial of service in n/a","id":"CVE-2007-3644","kev_date_added":null,"published":"2007-07-14"}],"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)"}],"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 potentially execute code via crafted TAR or ISO9660 archives in libarchive.","url":"https://insights.sbomify.com/CVE-2011-1779/"}
