More information:

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

  • CVE-2010-3677

    It was discovered that MySQL allows remote authenticated users to cause a denial of service (mysqld daemon crash) via a join query that uses a table with a unique SET column.

  • CVE-2010-3680

    It was discovered that MySQL allows remote authenticated users to cause a denial of service (mysqld daemon crash) by creating temporary tables while using InnoDB, which triggers an assertion failure.

  • CVE-2010-3681

    It was discovered that MySQL allows remote authenticated users to cause a denial of service (mysqld daemon crash) by using the HANDLER interface and performing "alternate reads from two indexes on a table," which triggers an assertion failure.

  • CVE-2010-3682

    It was discovered that MySQL incorrectly handled use of EXPLAIN with certain queries. An authenticated user could crash the server.

  • CVE-2010-3833

    It was discovered that MySQL incorrectly handled propagation during evaluation of arguments to extreme-value functions. An authenticated user could crash the server.

  • CVE-2010-3834

    It was discovered that MySQL incorrectly handled materializing a derived table that required a temporary table for grouping. An authenticated user could crash the server.

  • CVE-2010-3835

    It was discovered that MySQL incorrectly handled certain user-variable assignment expressions that are evaluated in a logical expression context. An authenticated user could crash the server.

  • CVE-2010-3836

    It was discovered that MySQL incorrectly handled pre-evaluation of LIKE predicates during view preparation. An authenticated user could crash the server.

  • CVE-2010-3837

    It was discovered that MySQL incorrectly handled using GROUP_CONCAT() and WITH ROLLUP together. An authenticated user could crash the server.

  • CVE-2010-3838

    It was discovered that MySQL incorrectly handled certain queries using a mixed list of numeric and LONGBLOB arguments to the GREATEST() or LEAST() functions. An authenticated user could crash the server.

  • CVE-2010-3840

    It was discovered that MySQL incorrectly handled improper WKB data passed to the PolyFromWKB() function. An authenticated user could crash the server.

For the stable distribution (lenny), these problems have been fixed in version 5.0.51a-24+lenny5.

The testing (squeeze) and unstable (sid) distribution do not contain mysql-dfsg-5.0 anymore.

We recommend that you upgrade your mysql-dfsg-5.0 packages.
