Date: November 10, 2017
Bugs: #635704, #635706
ID: 201711-04

Synopsis
========

A vulnerability was discovered in MariaDB and MySQL which may allow
local users to gain root privileges.

Background
==========

MySQL is a popular multi-threaded, multi-user SQL server. MariaDB is an
enhanced, drop-in replacement for MySQL.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/mariadb < 10.0.30-r1 >= 10.0.30-r1
2 dev-db/mysql < 5.6.36-r1 >= 5.6.36-r1
-------------------------------------------------------------------
2 affected packages

Description
===========

The Gentoo installation scripts before 2017-09-29 have chown calls for
user-writable directory trees, which allows local users to gain
privileges by leveraging access to the mysql account for creation of a
link.

Impact
======

A local attacker could escalate privileges to root.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MariaDB users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/mariadb-10.0.30-r1"

All MySQL users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-db/mysql-5.6.36-r1"
