Oracle MySQL 5.6.x < 5.6.31 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 9612

Synopsis

The remote database server is vulnerable to multiple attack vectors.

Description

The version of MySQL installed on the remote host is version 5.6.x prior to 5.6.31 and is affected by multiple issues :

- Multiple unspecified overflow conditions exist that are triggered as user-supplied input is not properly validated. This may allow an authenticated attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
- A NULL pointer dereference flaw exists in a parser structure that is triggered during the validation of stored procedure names. This may allow an authenticated attacker to potentially cause the database to crash.
- Multiple unspecified overflow conditions exist in the InnoDB memcached plugin that are triggered as user-supplied input is not properly validated. This may allow an authenticated attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
- A flaw exists that is triggered when invoking Enterprise Encryption functions in multiple threads simultaneously or after creating and dropping them. This may allow an authenticated attacker to potentially crash the database.
- A flaw exists that is triggered when handling a 'SELECT ... GROUP BY ... FOR UPDATE' query executed with a Loose Index Scan. This may allow an authenticated attacker to potentially crash the database.
- An unspecified flaw exists related to the InnoDB Plugin subcomponent. This may allow an authenticated remote attacker to have an impact on integrity. No further details have been provided by the vendor.

Solution

Upgrade to MySQL 5.6.31 or later.
