MySQL Denial of Service (infinite loop) Vulnerabilities

  1. Network Vulnerabilities
  2. Databases
  3. MySQL Denial of Service (infinite loop) Vulnerabilities
Summary
The host is running MySQL and is prone to denial of service vulnerabilities.
Impact
Successful exploitation could allow users to cause a denial of service and to execute arbitrary code. Impact Level: Application
Solution
Upgrade to MySQL version 5.1.51 or 5.5.6 For updates refer to http://dev.mysql.com/downloads
Insight
The flaws are due to: - Performing a user-variable assignment in a logical expression that is calculated and stored in a temporary table for GROUP BY, then causing the expression value to be used after the table is created, which causes the expression to be re-evaluated instead of accessing its value from the table. - An error in multiple invocations of a (1) prepared statement or (2) stored procedure that creates a query with nested JOIN statements.
Affected
MySQL 5.1 before 5.1.51 and 5.5 before 5.5.6
