Summary

The host is running MySQL and is prone to denial of service vulnerabilities.

Insight

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 Software

Affected Software

MySQL 5.1 before 5.1.51 and 5.5 before 5.5.6.
