The php-fpm master process restarts a child process in an endless loop when using program execution functions (e.g., passthru, exec, shell_exec, or system) with a non-blocking STDIN stream, causing this master process to consume 100% of the CPU, and consume disk space with a large volume of error logs, as demonstrated by an attack by a customer of a shared-hosting facility.","modified":"2026-11-03T06:30:06.725591289Z","published":"2018-02-19T19:29:00.483Z","upstream":["CVE-2015-9253"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2015-9253"}],"affected":[{"package":{"name":"php7","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}},{"package":{"name":"php7","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/php7?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.2.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2015-9253.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
