{"id":"CVE-2019-11046","details":"In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations.","modified":"2026-05-08T12:21:21.257Z","published":"2019-12-23T03:15:11.710Z","related":["SUSE-SU-2020:0101-1","SUSE-SU-2020:0267-1","SUSE-SU-2020:0352-1","SUSE-SU-2020:0522-1","SUSE-SU-2020:14289-1","SUSE-SU-2022:4067-1","openSUSE-SU-2020:0080-1","openSUSE-SU-2024:11167-1","openSUSE-SU-2024:11169-1"],"database_specific":{"unresolved_ranges":[{"cpe":"cpe:2.3:a:tenable:securitycenter:*:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"fixed":"5.19.0"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:12.04:*:*:*:-:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"12.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:esm:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"14.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:esm:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"16.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"18.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"19.04"}]},{"cpe":"cpe:2.3:o:canonical:ubuntu_linux:19.10:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"19.10"}]},{"cpe":"cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"10.0"}]},{"cpe":"cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"9.0"}]},{"cpe":"cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"30"}]},{"cpe":"cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"31"}]},{"cpe":"cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"last_affected":"15.1"}]}]},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/N7GCOAE6KVHYJ3UQ4KLPLTGSLX6IRVRN/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XWRQPYXVG43Q7DXMXH6UVWMKWGUW552F/"},{"type":"WEB","url":"https://support.f5.com/csp/article/K48866433?utm_source=f5support&amp%3Butm_medium=RSS"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00036.html"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/12/msg00034.html"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2020/Feb/27"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2020/Feb/31"},{"type":"ADVISORY","url":"https://seclists.org/bugtraq/2021/Jan/3"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20200103-0002/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4239-1/"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4626"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4628"},{"type":"ADVISORY","url":"https://www.tenable.com/security/tns-2021-14"},{"type":"FIX","url":"https://bugs.php.net/bug.php?id=78878"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/php/php-src","events":[{"introduced":"8148cbb78841c8ec0759c0836e7f35dec799d300"},{"last_affected":"1df155af14c3b7473b628574eb46a7ce11caadfd"},{"introduced":"52ace952a1b65ca80fc2617f11c2fa6dd03f51bd"},{"last_affected":"a1457cf8b8b82516bf9561eb43972b63074fa9ae"},{"introduced":"0"},{"last_affected":"3c7824e16ec4c3cee417262445d2c2b66531c10f"},{"last_affected":"5dc92c2117cafc61daaaaa240fd46c3ac33872a4"}],"database_specific":{"cpe":["cpe:2.3:a:php:php:*:*:*:*:*:*:*:*","cpe:2.3:a:php:php:7.4.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"introduced":"7.2.0"},{"last_affected":"7.2.26"},{"introduced":"7.3.0"},{"last_affected":"7.3.13"},{"introduced":"0"},{"last_affected":"7.4.0"},{"last_affected":"8.0"}]}}],"versions":["POST_64BIT_BRANCH_MERGE","POST_AST_MERGE","POST_PHP7_NSAPI_REMOVAL","POST_PHP7_REMOVALS","POST_PHPNG_MERGE","PRE_64BIT_BRANCH_MERGE","PRE_AST_MERGE","PRE_PHP7_EREG_MYSQL_REMOVALS","PRE_PHP7_NSAPI_REMOVAL","PRE_PHP7_REMOVALS","php-7.2.26","php-7.3.13","php-7.3.13RC1","php-7.4.0","php-8.0.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2019-11046.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
