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.

MySQL did not correctly handle NULL as the second argument to the str_to_date() function. An authenticated user could exploit this to crash the server.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

リモートホストにインストールされている MySQL のバージョンは、4.1.18 / 5.0.19 / 5.1.6 より前であり、このため、報告によると、リモートの認証されたユーザーが、str_to_date 関数を通じてサーバーをクラッシュさせる可能性があります。

远程主机上安装的 MySQL 版本低于 4.1.18 / 5.0.19 / 5.1.6，因此有报告称其允许经认证的远程用户通过 str_to_date 函数导致服务器崩溃。

遠端主機上安裝的 MySQL 版本比 4.1.18 / 5.0.19 / 5.1.6 舊，因此據報允許經驗證的遠端使用者透過 str_to_date 函式，造成伺服器當機。

The remote host is running a version of Mac OS X 10.4 which is older than version 10.4.9 or a version of Mac OS X 10.3 which does not have Security Update 2007-003 applied.

Several local vulnerabilities have been discovered in the MySQL database server, which may lead to denial of service. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-3081     'Kanatoko' discovered that the server can be crashed     with feeding NULL values to the str_to_date() function.

  - CVE-2006-3469     Jean-David Maillefer discovered that the server can be     crashed with specially crafted date_format() function     calls.

The version of MySQL installed on the remote host is earlier than 4.1.18 / 5.0.19 / 5.1.6 and thus reportedly allows a remote, authenticated user to crash the server via the str_to_date function.

Mysqld in MySQL 4.1.x before 4.1.18, 5.0.x before 5.0.19, and 5.1.x before 5.1.6 allows remote authorized users to cause a denial of service (crash) via a NULL second argument to the str_to_date function.

MySQL 4.0.18 in Corporate 3.0 and MNF 2.0 is not affected by this issue.

Packages have been patched to correct this issue.

According to its version number, the installation of MySQL on the remote host may be prone to multiple buffer overflows.  The MySQL server is also vulnerable to multiple information disclosure flaws.  An attacker exploiting the overflow would need to be able to authenticate to the MySQL server.  An attacker exploiting the information disclosure flaw would only need to be able to send malformed 'login' packets to the server. This version of MySQL is also prone to a remote Denial of Service (DoS) due to an inability to properly parse a malformed call to the date_format function.
