MySQL 5.1.x before 5.1.41 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 an incomplete fix for CVE-2008-4098 and CVE-2008-2079.
Note:References are provided for the convenience of the reader to help distinguish between vulnerabilities. The list is not intended to be complete.
