It can be exploited over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2012-6063 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-2012-6063/ (Markdown: https://insights.sbomify.com/CVE-2012-6063/index.md)","id":"CVE-2012-6063","markdown":"https://insights.sbomify.com/CVE-2012-6063/index.md","name":"CVE-2012-6063","record":{"aliases":["DEBIAN-CVE-2012-6063","GHSA-fgm4-g835-pxpp"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"libssh library","requires_auth":"unknown","summary":"A double free vulnerability in libssh allows remote attackers to cause a crash and potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libssh","vendor":"libssh"}],"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":"Double free vulnerability in the sftp_mkdir function in sftp.c in libssh before 0.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors, a different vector than CVE-2012-4559.","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-2012-6063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2012"},"n_packages":0,"n_references":4,"next":{"headline":"Path traversal in n/a","id":"CVE-2012-6064"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-6062"},"products":["n/a"],"published":"2012-11-30","related":[{"cvss_score":8.8,"headline":"Libssh: libssh: authentication bypass via missing gssapi principal check","id":"CVE-2026-59851","kev_date_added":null,"published":"2026-07-21"},{"cvss_score":8.1,"headline":"Libssh: invalid return code for chacha20 poly1305 with openssl backend","id":"CVE-2025-5987","kev_date_added":null,"published":"2025-07-07"},{"cvss_score":7.8,"headline":"Libssh: libssh: insecure default configuration leads to local man-in-the-middle attacks on windows","id":"CVE-2025-14821","kev_date_added":null,"published":"2026-04-07"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2012-4560","kev_date_added":null,"published":"2012-11-30"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2012-4562","kev_date_added":null,"published":"2012-11-30"},{"cvss_score":6.9,"headline":"libssh SFTP Extension Name sftp.c sftp_extensions_get_data out-of-bounds","id":"CVE-2026-3731","kev_date_added":null,"published":"2026-03-08"}],"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":"A double free vulnerability in libssh allows remote attackers to cause a crash and potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2012-6063/"}
