Synopsis

========

 

Multiple vulnerabilities in MySQL might lead to privilege escalation

and Denial of Service.

 

Background

==========

 

MySQL is a popular multi-threaded, multi-user SQL server.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 dev-db/mysql < 5.0.54 >= 5.0.54

 

Description

===========

 

Multiple vulnerabilities have been reported in MySQL:

 

* Mattias Jonsson reported that a "RENAME TABLE" command against a

table with explicit "DATA DIRECTORY" and "INDEX DIRECTORY" options

would overwrite the file to which the symlink points (CVE-2007-5969).

 

* Martin Friebe discovered that MySQL does not update the DEFINER

value of a view when the view is altered (CVE-2007-6303).

 

* Philip Stoev discovered that the federated engine expects the

response of a remote MySQL server to contain a minimum number of

columns in query replies (CVE-2007-6304).

 

Impact

======

 

An authenticated remote attacker could exploit the first vulnerability

to overwrite MySQL system tables and escalate privileges, or use the

second vulnerability to gain privileges via an "ALTER VIEW" statement.

Remote federated MySQL servers could cause a Denial of Service in the

local MySQL server by exploiting the third vulnerability.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All MySQL users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.54"
