| Description: | 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.
