CVE-2008-2079

MySQL 4.1.x anterior a 4.1.24, 5.0.x antes de 5.0.60, 5.1.x anterior a 5.1.24 y 6.0.x antes de 6.0.5 permite a usuarios locales evitar ciertas comprobaciones de privilegios llamando a CREATE TABLE en una tabla MyISAM con argumentos (1) DATA DIRECTORY or (2) INDEX DIRECTORY modificados que están dentro del directorio MySQL home data, que puede apuntar a tablas que se crearán en el futuro.

Multiple buffer overflows in yaSSL, which is used in MySQL, allowed remote attackers to execute arbitrary code. a denial of service via a special Hello packet. Sergei Golubchik found that MySQL did not properly validate optional data or index directory paths given in a CREATE TABLE statement; as well it would not, under certain conditions, prevent two databases from using the same paths for data or index files. This could allow an authenticated user with appropriate privilege to create tables in one database to read and manipulate data in tables later created in other databases, regardless of GRANT privileges. The updated packages have been patched to correct these issues.
