Synopsis
========

MySQL is vulnerable to an SQL Injection flaw in the multi-byte encoding
process.

Background
==========

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

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-db/mysql lt; 4.1.20 *gt;= 4.1.20
gt;= 5.0.22
dev-db/mysql lt; 5.0.22 *gt;= 4.1.20
gt;= 5.0.22

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

MySQL is vulnerable to an injection flaw in mysql_real_escape() when
used with multi-byte characters.

Impact
======

Due to a flaw in the multi-byte character process, an attacker is still
able to inject arbitary SQL statements into the MySQL server for
execution.

Workaround
==========

There are a few workarounds available: NO_BACKSLASH_ESCAPES mode as a
workaround for a bug in mysql_real_escape_string(): SET
sql_mode='NO_BACKSLASH_ESCAPES'; SET GLOBAL
sql_mode='NO_BACKSLASH_ESCAPES'; and server command line options:
--sql-mode=NO_BACKSLASH_ESCAPES.

Resolution
==========

All MySQL users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-db/mysql-4.1.20"

References
==========
