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.

Security readout for executives and security teams

This is an old MySQL local-privilege issue in which a user with local access could bypass certain database privilege checks through MyISAM table directory handling. The sources name MySQL 5.0.88 and note related exposure in Red Hat Enterprise Linux 6 MySQL 5.0.95. There is no public evidence in the bundle of active exploitation. Exposure is most likely on legacy MySQL deployments, especially MySQL 5.0.88 and the Red Hat Enterprise Linux 6 MySQL 5.0.95 package referenced by the CVE. The bundle does not establish broader affected-version boundaries. Treat as a targeted legacy-platform risk. It is not supported as internet-wormable from the sources, but local database privilege bypass can matter on shared hosting, multi-user servers, or old regulated environments still running unsupported MySQL packages. Mitigation focus: Review vendor advisories, especially RHSA-2013:0121 for applicable Red Hat systems.; Upgrade or replace affected legacy MySQL packages using vendor-supported guidance.; Restrict local database access to trusted users only..
