Oracle MySQL 5.7.x < 5.7.5 DoS

Medium Nessus Network Monitor Plugin ID 9939


The remote database server is vulnerable to a Denial of Service (DoS) attack vector.


The version of MySQL installed on the remote host is version 5.7.x prior to 5.7.5 and is affected by a use-after-free error in the 'mysql_prune_stmt_list()' function in 'client.c' that may allow an authenticated attacker to dereference already freed memory and crash the database.


Upgrade to MySQL 5.7.5 or later.
