mysql security update

CentOS Errata and Security Advisory CESA-2006:0544

MySQL is a multi-user, multi-threaded SQL database server. MySQL is a
client/server implementation consisting of a server daemon (mysqld) and
many different client programs and libraries.

A flaw was found in the way the MySQL mysql_real_escape() function escaped
strings when operating in a multibyte character encoding. An attacker
could provide an application a carefully crafted string containing
invalidly-encoded characters which may be improperly escaped, leading to
the injection of malicious SQL commands. (CVE-2006-2753)

An information disclosure flaw was found in the way the MySQL server
processed malformed usernames. An attacker could view a small portion
of server memory by supplying an anonymous login username which was not
null terminated. (CVE-2006-1516)

An information disclosure flaw was found in the way the MySQL server
executed the COM_TABLE_DUMP command. An authenticated malicious user could
send a specially crafted packet to the MySQL server which returned
random unallocated memory. (CVE-2006-1517)

A log file obfuscation flaw was found in the way the mysql_real_query()
function creates log file entries. An attacker with the the ability to call
the mysql_real_query() function against a mysql server can obfuscate the
entry the server will write to the log file. However, an attacker needed
to have complete control over a server in order to attempt this attack.
(CVE-2006-0903)

This update also fixes numerous non-security-related flaws, such as
intermittent authentication failures.

All users of mysql are advised to upgrade to these updated packages
containing MySQL version 4.1.20, which is not vulnerable to these issues.
