MariaDB Server 10.1.x < 10.1.19 Multiple Vulnerabilities

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 10.1.19, and is therefore affected by multiple vulnerabilities :

• A flaw exists in the ‘buf_page_is_checksum_valid*’ function in ‘buf0buf.cc’ that is triggered during the handling of encrypted information. This may allow an authenticated attacker to cause a denial of service.
• A flaw exists in the ‘wsrep_replicate_myisam’ functionality that is triggered when dropping ‘myisam’ tables. This may allow an authenticated attacker to crash the database.

Depending on the database’s implementation, it varies if these vulnerabilitues require authenticated access (e.g. daily DBA duties) or may be exploited by a remote attacker (e.g. interfaced via a web application).

• An unspecified flaw exists in the Security: Encryption subcomponent that allows an authenticated, remote attacker to disclose sensitive information. (CVE-2016-5584)
• A flaw exists in wolfSSL, specifically within the C software version of AES Encryption and Decryption, due to table lookups not properly considering cache-bank access times. A local attacker can exploit this, via a specially crafted application, to disclose AES keys. Note that this vulnerability does not affect MariaDB packages included in Red Hat products since they’re built against system OpenSSL packages. (CVE-2016-7440)
