Mandriva Linux Security Advisory : mysql (MDVSA-2010:012)
Medium Nessus Plugin ID 48166
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple vulnerabilities has been found and corrected in mysql :
mysqld in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41 does not (1) properly handle errors during execution of certain SELECT statements with subqueries, and does not (2) 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-2009-4019).
The vio_verify_callback function in viosslfactories.c in MySQL 5.0.x before 5.0.88 and 5.1.x before 5.1.41, when OpenSSL is used, accepts a value of zero for the depth of X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary SSL-based MySQL servers via a crafted certificate, as demonstrated by a certificate presented by a server linked against the yaSSL library (CVE-2009-4028).
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 (CVE-2009-4030).
The updated packages have been patched to correct these issues.
Additionally for 2009.1 and 2010.0 mysql has also been upgraded to the latest stable 5.1 release (5.1.42).
SolutionUpdate the affected packages.
