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 < 4.1.20 *>= 4.1.20
>= 5.0.22
dev-db/mysql < 5.0.22 *>= 4.1.20
>= 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 ">=dev-db/mysql-4.1.20"
References
==========
