Summary
a @variableCVE-2009-4028 mysql: client SSL certificate verification flawCVE-2009-4030 mysql: Incomplete fix for CVE-2008-2079 / CVE-2008-4098It was discovered that the MySQL client ignored certain SSL certificateverification errors when connecting to servers. A man-in-the-middleattacker could use this flaw to trick MySQL clients into connecting to aspoofed MySQL server. (CVE-2009-4028)Note: This fix may uncover previously hidden SSL configuration issues,such as incorrect CA certificates being used by clients or expiredserver certificates. This update should be carefully tested indeployments where SSL connections are used.A flaw was found in the way MySQL handled SELECT statements withsubqueries in the WHERE clause, that assigned results to a uservariable. A remote, authenticated attacker could use this flaw to crashthe MySQL server daemon (mysqld). This issue only caused a temporarydenial of service, as the MySQL daemon was automatically restarted afterthe crash. (CVE-2009-4019)When the "datadir" option was configured with a relative path, MySQL didnot properly check paths used as arguments for the DATA DIRECTORY andINDEX DIRECTORY directives. An authenticated attacker could use thisflaw to bypass the restriction preventing the use of subdirectories ofthe MySQL data directory being used as DATA DIRECTORY and INDEXDIRECTORY paths. (CVE-2009-4030)Note: Due to the security risks and previous security issues related tothe use of the DATA DIRECTORY and INDEX DIRECTORY directives, users notdepending on this feature should consider disabling it by adding"symbolic-links=0" to the "[mysqld]" section of the "my.cnf"configuration file. In this update, an example of such a configurationwas added to the default "my.cnf" file.After installing this update, the MySQL server daemon (mysqld) will berestarted automatically.SL 5.xSRPMS:mysql-5.0.77-4.el5_4.2.src.rpmi386:mysql-5.0.77-4.el5_4.2.i386.rpmmysql-bench-5.0.77-4.el5_4.2.i386.rpmmysql-devel-5.0.77-4.el5_4.2.i386.rpmmysql-server-5.0.77-4.el5_4.2.i386.rpmmysql-test-5.0.77-4.el5_4.2.i386.rpmx86_64:mysql-5.0.77-4.el5_4.2.i386.rpmmysql-5.0.77-4.el5_4.2.x86_64.rpmmysql-bench-5.0.77-4.el5_4.2.x86_64.rpmmysql-devel-5.0.77-4.el5_4.2.i386.rpmmysql-devel-5.0.77-4.el5_4.2.x86_64.rpmmysql-server-5.0.77-4.el5_4.2.x86_64.rpmmysql-test-5.0.77-4.el5_4.2.x86_64.rpm-Connie Sieh-Troy Dawson
