CVE-2009-4030 mysql: Incomplete fix for CVE-2008-2079 / CVE-2008-4098



Multiple flaws were discovered in the way MySQL handled symbolic links 

to tables created using the DATA DIRECTORY and INDEX DIRECTORY 

directives in CREATE TABLE statements. An attacker with CREATE and DROP 

table privileges and shell access to the database server could use these 

flaws to escalate their database privileges, or gain access to tables 

created by other database users. (CVE-2008-4098, CVE-2009-4030)



Note: Due to the security risks and previous security issues related to 

the use of the DATA DIRECTORY and INDEX DIRECTORY directives, users not

depending 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 configuration 

was added to the default "my.cnf" file.



An insufficient HTML entities quoting flaw was found in the mysql 

command line client's HTML output mode. If an attacker was able to 

inject arbitrary HTML tags into data stored in a MySQL database, which 

was later retrieved using the mysql command line client and its HTML 

output mode, they could perform a cross-site scripting (XSS) attack 

against victims viewing the HTML output in a web browser. (CVE-2008-4456)



Multiple format string flaws were found in the way the MySQL server 

logged user commands when creating and deleting databases. A remote, 

authenticated attacker with permissions to CREATE and DROP databases 

could use these flaws to formulate a specially-crafted SQL command that 

would cause a temporary denial of service (open connections to mysqld 

are terminated). (CVE-2009-2446)



Note: To exploit the CVE-2009-2446 flaws, the general query log (the 

mysqld "--log" command line option or the "log" option in "my.cnf") must 

be enabled. This logging is not enabled by default.



After installing this update, the MySQL server daemon (mysqld) will be 

restarted automatically.
