Synopsis
The remote database server is affected by multiple Denial of Service (DoS) attack vectors.
Description
MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 10.1.x earlier than 10.1.7, and is therefore affected by the following denial of service vulnerabilities :
- A flaw exists in the 'my_multi_malloc()' function that is triggered when trying to allocate a key cache of more than 45G with a 'key_cache_block_size' of 1024 or less. This may allow an authenticated attacker to potentially cause a buffer overflow and have an unspecified impact.
- A flaw exists in the 'page_cur_is_after_last()' function that is triggered when handling table alteration encryption keys. This may allow an authenticated attacker to cause the server to crash.
Solution
Upgrade to version 10.1.7 or later.
