Oracle MySQL 5.7.x < 5.7.17 Multiple Vulnerabilities

High

Synopsis

The remote database server is vulnerable to multiple attack vectors.

Description

The version of MySQL installed on the remote host is version 5.7.x prior to 5.7.17 and is affected by multiple issues :

- A flaw exists in 'mysqld_safe' that is due to the unsafe use of 'rm' and 'chown'. This may allow an authenticated local attacker to gain elevated privileges. (OSVDB 148580) - An unspecified flaw exists in 'mysqld_safe' that is due to the program ignoring the current working directory. This may allow an authenticated attacker to have an unspecified impact. No further details have been provided. (OSVDB 148581) - An overflow condition exists in the Optimizer. The issue is triggered as certain input is not properly validated when handling nested expressions. This may allow an authenticated attacker to cause a stack-based buffer overflow, resulting in a denial of service. (OSVDB 148582) - A flaw exists that is triggered during the handling of a 'CREATE TABLE' query with a 'DATA DIRECTORY' clause. This may allow an authenticated attacker to gain elevated privileges. (OSVDB 148583)

Solution

Upgrade to MySQL 5.7.17 or later.
