"Updated mysql packages that fix multiple security flaws are now
available.

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.
(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."
