An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-4073 in the wild and no public exploit code.\n\nAffected product: Apple Mac Os X. 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-2016-4073/ (Markdown: https://insights.sbomify.com/CVE-2016-4073/index.md)","id":"CVE-2016-4073","markdown":"https://insights.sbomify.com/CVE-2016-4073/index.md","name":"CVE-2016-4073","record":{"aliases":["GHSA-3fjc-9f6x-jrfx","UBUNTU-CVE-2016-4073"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP mbstring extension","requires_auth":"none","summary":"Remote attackers can cause a crash or execute arbitrary code via crafted mb_strcut calls due to integer overflows in the PHP mbstring extension.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mac_os_x","vendor":"apple"},{"product":"php","vendor":"php"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Multiple integer overflows in the mbfl_strcut function in ext/mbstring/libmbfl/mbfl/mbfilter.c in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted mb_strcut call.","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":"Integer overflow in n/a","id":"CVE-2016-4073","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:mac_os_x","products":["apple:mac_os_x","php:php"],"type":"integer_overflow","year":"2016"},"n_packages":0,"n_references":18,"next":{"headline":"Denial of service in n/a","id":"CVE-2016-4074"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2016-4072"},"products":["n/a"],"published":"2016-05-20","related":[{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-7169","kev_date_added":"2022-01-28","published":"2014-09-25"},{"cvss_score":9.8,"headline":"GNU Bourne-Again Shell (Bash) Arbitrary Code Execution","id":"CVE-2014-6271","kev_date_added":"2022-01-28","published":"2014-09-24"},{"cvss_score":9.8,"headline":"PHP-CGI Query String Parameter","id":"CVE-2012-1823","kev_date_added":"2022-03-25","published":"2012-05-11"},{"cvss_score":7.8,"headline":"Apple macOS Unspecified","id":"CVE-2021-30713","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":7.8,"headline":"Apple macOS Use-After-Free","id":"CVE-2019-8526","kev_date_added":"2023-04-17","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple OS X Authentication Bypass","id":"CVE-2015-1130","kev_date_added":"2022-02-10","published":"2015-04-10"},{"cvss_score":5.5,"headline":"Apple macOS Out-of-Bounds Read","id":"CVE-2022-22674","kev_date_added":"2022-04-04","published":"2022-05-26"}],"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 a crash or execute arbitrary code via crafted mb_strcut calls due to integer overflows in the PHP mbstring extension.","url":"https://insights.sbomify.com/CVE-2016-4073/"}
