CVE-2016-6663 – MySQL / MariaDB / PerconaDB 5.5.x/5.6.x/5.7.x - 'mysql' System User Privilege Escalation / Race Condition
https://notcve.org/view.php?id=CVE-2016-6663
Race condition in Oracle MySQL before 5.5.52, 5.6.x before 5.6.33, 5.7.x before 5.7.15, and 8.x before 8.0.1; MariaDB before 5.5.52, 10.0.x before 10.0.28, and 10.1.x before 10.1.18; Percona Server before 5.5.51-38.2, 5.6.x before 5.6.32-78-1, and 5.7.x before 5.7.14-8; and Percona XtraDB Cluster before 5.5.41-37.0, 5.6.x before 5.6.32-25.17, and 5.7.x before 5.7.14-26.17 allows local users with certain permissions to gain privileges by leveraging use of my_copystat by REPAIR TABLE to repair a MyISAM table. Condición de carrera en Oracle MySQL en versiones anteriores a 5.5.52, 5.6.x en versiones anteriores a 5.6.33, 5.7.x en versiones anteriores a 5.7.15 y 8.x en versiones anteriores a 8.0.1; MariaDB en versiones anteriores a 5.5.52, 10.0.x en versiones anteriores a 10.0.28 y 10.1.x en versiones anteriores a 10.1.18; Percona Server en versiones anteriores a 5.5.51-38.2, 5.6.x en versiones anteriores a 5.6.32-78-1 y 5.7.x en versiones anteriores a 5.7.14-8 y Percona XtraDB Cluster en versiones anteriores a 5.5.41-37.0, 5.6.x en versiones anteriores a 5.6.32-25.17 y 5.7.x en versiones anteriores a 5.7.14-26.17 permite a usuarios locales con ciertos permisos obtener privilegios aprovechando el uso de my_copystat por REPAIR TABLE para reparar una tabla MyISAM. A race condition was found in the way MySQL performed MyISAM engine table repair. A database user with shell access to the server running mysqld could use this flaw to change permissions of arbitrary files writable by the mysql system user. An independent research has revealed a race condition vulnerability which affects MySQL, MariaDB and PerconaDB databases. • https://www.exploit-db.com/exploits/40678 https://github.com/firebroo/CVE-2016-6663 http://rhn.redhat.com/errata/RHSA-2016-2130.html http://rhn.redhat.com/errata/RHSA-2016-2131.html http://rhn.redhat.com/errata/RHSA-2016-2595.html http://rhn.redhat.com/errata/RHSA-2016-2749.html http://rhn.redhat.com/errata/RHSA-2016-2927.html http://rhn.redhat.com/errata/RHSA-2016-2928.html http://rhn.redhat.com/errata/RHSA-2017-0184.html http://seclists.org/fulldisclosure • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
