http://security.gentoo.org/

Severity:	normal
Title:	MySQL: SQL Injection
Date:	06/11/2006
Bugs:	#135076
ID:	200606-13

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	Architecture(s)
dev-db/mysql	< 5.0.22	>= 5.0.22	All supported architectures

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"
