It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-5596 exists.\n\nAffected product: Freebsd Freebsd. 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-2019-5596/ (Markdown: https://insights.sbomify.com/CVE-2019-5596/index.md)","id":"CVE-2019-5596","markdown":"https://insights.sbomify.com/CVE-2019-5596/index.md","name":"CVE-2019-5596","record":{"aliases":["GHSA-89xf-9vcr-5475"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FreeBSD kernel","requires_auth":"low_privilege","summary":"A use-after-free bug in FreeBSD UNIX domain sockets allows local attackers to gain root privileges or escape jails.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"In FreeBSD 11.2-STABLE after r338618 and before r343786, 12.0-STABLE before r343781, and 12.0-RELEASE before 12.0-RELEASE-p3, a bug in the reference count implementation for UNIX domain sockets can cause a file structure to be incorrectly released potentially allowing a malicious local user to gain root privileges or escape from a jail.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2019-07-10","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-03-29T09:15:07Z","kind":"github_poc","ref":"https://github.com/raymontag/CVE-2019-5596","stars":1,"title":"Full LPE Exploit for CVE-2019-5596 / FreeBSD-SA-19:02.fd"},{"date":"2019-07-10","kind":"exploitdb","ref":"47081","stars":null,"title":"FreeBSD 12.0 - 'fd' Local Privilege Escalation"},{"date":"2019-12-30","kind":"exploitdb","ref":"47829","stars":null,"title":"FreeBSD-SA-19:02.fd - Privilege Escalation"}],"tier":"weaponised"},"has_fix":null,"headline":"Use after free in FreeBSD","id":"CVE-2019-5596","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freebsd:freebsd","products":["freebsd:freebsd"],"type":"use_after_free","year":"2019"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in FreeBSD","id":"CVE-2019-5597"},"packages":[],"prev":{"headline":"Information disclosure in FreeBSD","id":"CVE-2019-5595"},"products":["FreeBSD"],"published":"2019-02-12","related":[{"cvss_score":10,"headline":"Memory corruption in FreeBSD","id":"CVE-2018-17160","kev_date_added":null,"published":"2018-12-04"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-3954","kev_date_added":null,"published":"2014-10-27"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-4304","kev_date_added":null,"published":"2006-08-24"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2006-0226","kev_date_added":null,"published":"2006-01-19"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2004-0002","kev_date_added":null,"published":"2004-02-03"},{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2001-0969","kev_date_added":null,"published":"2002-03-09"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2001-0388","kev_date_added":null,"published":"2001-09-18"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["FreeBSD"]},"summary":"A use-after-free bug in FreeBSD UNIX domain sockets allows local attackers to gain root privileges or escape jails.","url":"https://insights.sbomify.com/CVE-2019-5596/"}
