CONECTIVA LINUX SECURITY ANNOUNCEMENT
- --------------------------------------------------------------------------
PACKAGE : MySQL
SUMMARY : MySQL log file with world-readable permissions
DATE : 2002-01-18 16:14:00
ID : CLA-2002:455
RELEVANT
RELEASES : 5.0, 5.1, 6.0
- -------------------------------------------------------------------------
DESCRIPTION
MySQL is a very popular SQL database which is shipped by many linux
distributions.
The package shipped with Conectiva Linux 6.0 and older logs by
default all queries made to the database to the /var/log/mysql file.
This includes user creation, password changes via SQL commands and
other queries. Our package incorrectly leaves the permissions of this
file as world-readable (0644), thus allowing any user on the system
access to potentially sensitive information.
We believe this vulnerability[1,4] to be exclusive to our
distribution of this package.
Additionally, a few other problems[2,3] are also fixed in this
update. Specifically:
- logrotate now correctly restarts the server and rotates the logs.
Previous packages failed to do that and the log file would just keep
growing.
- logging is now configurable via the /etc/sysconfig/mysql file. The
default still has logging enabled, though.
SOLUTION
We recommend that all MySQL users upgrade their packages.
If an upgrade cannot be made at this time, please change the
permissions of the log file manually:
chmod 600 /var/log/mysql*
chown mysql.mysql /var/log/mysql*
