"Several vulnerabilities have been discovered in the MySQL database
server. The Common Vulnerabilities and Exposures project identifies
the following problems :

  - CVE-2009-4019
    Domas Mituzas discovered that mysqld does not properly
    handle errors during execution of certain SELECT
    statements with subqueries, and does not preserve
    certain null_value flags during execution of statements
    that use the GeomFromWKB function, which allows remote
    authenticated users to cause a denial of service (daemon
    crash) via a crafted statement.

  - CVE-2009-4030
    Sergei Golubchik discovered that MySQL allows local
    users to bypass certain privilege checks by calling
    CREATE TABLE on a MyISAM table with modified DATA
    DIRECTORY or 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.

  - CVE-2009-4484
    Multiple stack-based buffer overflows in the
    CertDecoder::GetName function in src/asn.cpp in TaoCrypt
    in yaSSL before 1.9.9, as used in mysqld, allow remote
    attackers to execute arbitrary code or cause a denial of
    service (memory corruption and daemon crash) by
    establishing an SSL connection and sending an X.509
    client certificate with a crafted name field."
