Descriptions

MySQL 5.0.88, and possibly other versions and platforms, allows local users to bypass certain privilege checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY arguments that are originally associated with pathnames without symlinks, and that can point to tables created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value. NOTE: this vulnerability exists because of a CVE-2009-4030 regression, which was not omitted in other packages and versions such as MySQL 5.0.95 in Red Hat Enterprise Linux 6.

MySQL v5.0.88 enlaces simbólicos, y posiblemente otras versiones y plataformas, permite a usuarios locales eludir ciertos privilegios llamando a CREATE TABLE en una tabla MyISAM con argumentos (1) DATA DIRECTORY o (2) INDEX DIRECTORY modificados que son originalmente asociados con rutas sin enlaces simbólicos, y que pueden apuntar a tablas creadas en un momento futuro en el que una ruta es modificada para contener un enlace simbólico a un subdirectorio del directorio de datos de MySQL. Se trata de un problema relacionado con el cálculo incorrecto del valor mysql_unpacked_real_data_home . NOTA: esta vulnerabilidad se debe a una regresión al CVE-2009-4030, que no fue evitado en algunos paquetes y versiones probados, como MySQL v5.0.95 en Red Hat Enterprise Linux 6.
