CVE-2006-4227

Description:
Two vulnerabilities have been reported in MySQL, which can be exploited by malicious users to bypass certain security restrictions and perform certain actions with escalated privileges.
1) A user, who has been granted access to a certain database but not privileges to create additional databases, can create a database where the name differs only by the case of one or more letters from the database which the user has access to.
Successful exploitation requires that MySQL runs on a system with a file system supporting case-sensitive file names.
2) An error caused due to arguments to suid routines being calculated in an incorrect security context can be exploited to execute arbitrary DML statements with the privileges of the routine's definer via a stored routine.
Successful exploitation requires that the user has "EXECUTE" privileges on the stored routine.
Solution:
The vulnerabilities have been fixed in the CVS repository and will also be fixed in the upcoming 5.0.25 version.
