MySQL before 4.1.13 allows local users to cause a denial of service (persistent replication slave crash) via a query with multiupdate and subselects.

The version of MySQL installed on the remote host is older than 4.1.13.  On these versions, a local attacker could crash the replication slave via a specific query.

MySQL before 4.1.13 allows local users to cause a denial of service (persistent replication slave crash) via a query with multiupdate and subselects. (CVE-2006-4380)

There is a bug in the MySQL-Max (and MySQL) init script where the script was not waiting for the mysqld daemon to fully stop. This impacted the restart behavior during updates, as well as scripted setups that temporarily stopped the server to backup the database files. (Bug #15724)

The Corporate 3 and MNF2 products are not affected by these issues.

Packages have been patched to correct these issues.

Several local vulnerabilities have been discovered in the MySQL database server. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-4226     Michal Prokopiuk discovered that remote authenticated     users are permitted to create and access a database if     the lowercase spelling is the same as one they have been     granted access to.

  - CVE-2006-4380     Beat Vontobel discovered that certain queries replicated     to a slave could crash the client and thus terminate the     replication.

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.
