The my_net_skip_rest function in sql/net_serv.cc in MySQL 5.0 through 5.0.91 and 5.1 before 5.1.47 allows remote attackers to cause a denial of service (CPU and bandwidth consumption) by sending a large number of packets that exceed the maximum length.

From Red Hat Security Advisory 2012:0127 :

Updated mysql packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

This update fixes several vulnerabilities in the MySQL database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section.
(CVE-2012-0075, CVE-2012-0087, CVE-2012-0101, CVE-2012-0102, CVE-2012-0114, CVE-2012-0484, CVE-2012-0490)

Update to MySQL 5.1.47, for various fixes described at http://dev.mysql.com/doc/refman/5.1/en/news-5-1-47.html including fixes for CVE-2010-1848, CVE-2010-1849, CVE-2010-1850 In F13, also create mysql group explicitly in pre-server script, to ensure correct GID

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

Versions of MySQL server earlier than 5.1.47 / 5.0.91 are potentially affected by the following vulnerabilities :

  - The server may continue reading packets indefinitely if it receives a packet larger than the maximum size of one packet, which could allow an unauthenticated remote attacker to consume a high level of CPU and bandwidth. (Bug #50974)

  - Using an overly long table name argument to the 'COM_FIELD_LIST' command, an authenticated user can overflow a buffer and execute arbitrary code on the affected host. (Bug #53237)

  - Using a specially crafted table name argument to 'COM_FIELD_LIST', an authenticated user can bypass almost all forms of checks for privileges and table-level grants. (Bug #53371)

It was discovered that MySQL did not check privileges before uninstalling plugins. An authenticated user could uninstall arbitrary plugins, bypassing intended restrictions. This issue only affected Ubuntu 9.10 and 10.04 LTS. (CVE-2010-1621)

It was discovered that MySQL could be made to delete another user's data and index files. An authenticated user could use symlinks combined with the DROP TABLE command to possibly bypass privilege checks. (CVE-2010-1626)

It was discovered that MySQL incorrectly validated the table name argument of the COM_FIELD_LIST command. An authenticated user could use a specially- crafted table name to bypass privilege checks and possibly access other tables. (CVE-2010-1848)

Eric Day discovered that MySQL incorrectly handled certain network packets. A remote attacker could exploit this flaw and cause the server to consume all available resources, resulting in a denial of service. (CVE-2010-1849)

It was discovered that MySQL performed incorrect bounds checking on the table name argument of the COM_FIELD_LIST command. An authenticated user could use a specially crafted table name to cause a denial of service or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. (CVE-2010-1850).

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.

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

  - CVE-2010-1626     MySQL allows local users to delete the data and index     files of another user's MyISAM table via a symlink     attack in conjunction with the DROP TABLE command.

  - CVE-2010-1848     MySQL failed to check the table name argument of a     COM_FIELD_LIST command packet for validity and     compliance to acceptable table name standards. This     allows an authenticated user with SELECT privileges on     one table to obtain the field definitions of any table     in all other databases and potentially of other MySQL     instances accessible from the server's file system.

  - CVE-2010-1849     MySQL could be tricked to read packets indefinitely if     it received a packet larger than the maximum size of one     packet. This results in high CPU usage and thus denial     of service conditions.

  - CVE-2010-1850     MySQL was susceptible to a buffer-overflow attack due to     a failure to perform bounds checking on the table name     argument of a COM_FIELD_LIST command packet. By sending     long data for the table name, a buffer is overflown,     which could be exploited by an authenticated user to     inject malicious code.

Multiple vulnerabilities has been found and corrected in mysql :

The server failed to check the table name argument of a COM_FIELD_LIST command packet for validity and compliance to acceptable table name standards. This could be exploited to bypass almost all forms of checks for privileges and table-level grants by providing a specially crafted table name argument to COM_FIELD_LIST (CVE-2010-1848).

The server could be tricked into reading packets indefinitely if it received a packet larger than the maximum size of one packet CVE-2010-1849).

The server was susceptible to a buffer-overflow attack due to a failure to perform bounds checking on the table name argument of a COM_FIELD_LIST command packet. By sending long data for the table name, a buffer is overflown, which could be exploited by an authenticated user to inject malicious code (CVE-2010-1850).

Packages for 2008.0 and 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:
http://store.mandriva.com/product_info.php?cPath=149&amp;products_id=4 90

The updated packages have been patched to correct these issues.

The version of MySQL Community Server installed on the remote host is earlier than 5.1.47 / 5.0.91 and is, therefore, potentially affected by the following vulnerabilities :

  - The server may continue reading packets indefinitely     if it receives a packet larger than the maximum size     of one packet, which could allow an unauthenticated,     remote attacker to consume a high level of CPU     and bandwidth. (Bug #50974)

  - Using an overly long table name argument to the     'COM_FIELD_LIST' command, an authenticated user can     overflow a buffer and execute arbitrary code on the     affected host. (Bug #53237)

  - Using a specially crafted table name argument to     'COM_FIELD_LIST', an authenticated user can bypass     almost all forms of checks for privileges and table-     level grants. (Bug #53371)
