Mandriva Linux Security Advisory 2009:326: mysql

Multiple vulnerabilities has been found and corrected in mysql:

MySQL 5.0 before 5.0.66, 5.1 before 5.1.26, and 6.0 before 6.0.6
does not properly handle a b'' (b single-quote single-quote) token,
aka an empty bit-string literal, which allows remote attackers to
cause a denial of service (daemon crash) by using this token in a
SQL statement (CVE-2008-3963).

MySQL before 5.0.67 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 home data
directory. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2008-4097 (CVE-2008-4098).

Cross-site scripting (XSS) vulnerability in the command-line client
in MySQL 5.0.26 through 5.0.45, when the --html option is enabled,
allows attackers to inject arbitrary web script or HTML by placing
it in a database cell, which might be accessed by this client when
composing an HTML document (CVE-2008-4456).

Multiple format string vulnerabilities in the dispatch_command function
in libmysqld/ in mysqld in MySQL 4.0.0 through 5.0.83 allow
remote authenticated users to cause a denial of service (daemon crash)
and possibly have unspecified other impact via format string specifiers
in a database name in a (1) COM_CREATE_DB or (2) COM_DROP_DB request.
NOTE: some of these details are obtained from third party information

Packages for 2008.0 are being provided due to extended support for
Corporate products.

This update provides fixes for this vulnerability.
