Description


Eric Romang has reported a vulnerability in MySQL, which can be exploited by malicious, local users to conduct various actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to the mysql_install_db script creating the temporary file "mysql_install_db.$$" insecurely. This can be exploited to overwrite arbitrary files with the privileges of the user running the vulnerable script via symlink attacks or execute arbitrary SQL commands by manipulating the file's contents.

The vulnerability has been reported in versions 4.1.11 and prior and development release 5.0.4 and prior.


Solution:
Update to version 4.1.12.
