Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated mysql packages that fix multiple security flaws are now

This update has been rated as having important security impact by the
Red Hat Security Response Team.

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.

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
