It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-7453 in the wild and no public exploit code.\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-2020-7453/ (Markdown: https://insights.sbomify.com/CVE-2020-7453/index.md)","id":"CVE-2020-7453","markdown":"https://insights.sbomify.com/CVE-2020-7453/index.md","name":"CVE-2020-7453","record":{"aliases":["GHSA-329c-g8g4-89hm"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"FreeBSD kernel","requires_auth":"high_privilege","summary":"A missing null termination check in FreeBSD's jail_set allows a malicious jail superuser to read kernel memory via jail_get.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"freebsd","cpe":[{"product":"freebsd","vendor":"freebsd"}],"cvss":{"score":6,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"In FreeBSD 12.1-STABLE before r359021, 12.1-RELEASE before 12.1-RELEASE-p3, 11.3-STABLE before r359020, and 11.3-RELEASE before 11.3-RELEASE-p7, a missing null termination check in the jail_set configuration option \"osrelease\" may return more bytes with a subsequent jail_get system call allowing a malicious jail superuser with permission to create nested jails to read kernel memory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Information disclosure in FreeBSD","id":"CVE-2020-7453","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"freebsd:freebsd","products":["freebsd:freebsd"],"type":"information_disclosure","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in FreeBSD","id":"CVE-2020-7454"},"packages":[],"prev":{"headline":"Memory corruption in FreeBSD","id":"CVE-2020-7452"},"products":["FreeBSD"],"published":"2020-04-28","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":"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":"2024-08-04","vendors":["n/a"]},"summary":"A missing null termination check in FreeBSD's jail_set allows a malicious jail superuser to read kernel memory via jail_get.","url":"https://insights.sbomify.com/CVE-2020-7453/"}
