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-2015-4021 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-2015-4021/ (Markdown: https://insights.sbomify.com/CVE-2015-4021/index.md)","id":"CVE-2015-4021","markdown":"https://insights.sbomify.com/CVE-2015-4021/index.md","name":"CVE-2015-4021","record":{"aliases":["GHSA-42r5-64j2-gjmp","UBUNTU-CVE-2015-4021"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP phar extension","requires_auth":"none","summary":"Remote attackers can cause denial of service via integer underflow and memory corruption in PHP's phar extension by crafting a malicious tar archive.","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"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_hpc_node","vendor":"redhat"},{"product":"enterprise_linux_hpc_node_eus","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \\0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive.","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-2015-4021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:mac_os_x","products":["apple:mac_os_x","php:php","redhat:enterprise_linux","redhat:enterprise_linux_desktop","redhat:enterprise_linux_hpc_node","redhat:enterprise_linux_hpc_node_eus","redhat:enterprise_linux_server","redhat:enterprise_linux_server_eus","redhat:enterprise_linux_workstation"],"type":"integer_overflow","year":"2015"},"n_packages":0,"n_references":18,"next":{"headline":"Integer overflow in n/a","id":"CVE-2015-4022"},"packages":[],"prev":{"headline":"RubyGems Improper Input Validation vulnerability","id":"CVE-2015-4020"},"products":["n/a"],"published":"2015-06-09","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 denial of service via integer underflow and memory corruption in PHP's phar extension by crafting a malicious tar archive.","url":"https://insights.sbomify.com/CVE-2015-4021/"}
