RHSA-2016:1132 - Security Advisory

Topic

An update for rh-mariadb100-mariadb is now available for Red Hat Software Collections.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

MariaDB is a multi-user, multi-threaded SQL database server. For all practical purposes, MariaDB is binary-compatible with MySQL. MariaDB uses PCRE, a Perl-compatible regular expression library, to implement regular expression support in SQL queries.

Security Fix(es):

• It was found that the MariaDB client library did not properly check host names against server identities noted in the X.509 certificates when establishing secure connections using TLS/SSL. A man-in-the-middle attacker could possibly use this flaw to impersonate a server to a client. (CVE-2016-2047)
• This update fixes several vulnerabilities in the MariaDB database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section. (CVE-2015-4792, CVE-2015-4802, CVE-2015-4815, CVE-2015-4816, CVE-2015-4819, CVE-2015-4826, CVE-2015-4830, CVE-2015-4836, CVE-2015-4858, CVE-2015-4861, CVE-2015-4870, CVE-2015-4879, CVE-2015-4895, CVE-2015-4913, CVE-2016-0505, CVE-2016-0546, CVE-2016-0596, CVE-2016-0597, CVE-2016-0598, CVE-2016-0600, CVE-2016-0606, CVE-2016-0608, CVE-2016-0609, CVE-2016-0610, CVE-2016-0616, CVE-2016-0640, CVE-2016-0641, CVE-2016-0642, CVE-2016-0643, CVE-2016-0644, CVE-2016-0646, CVE-2016-0647, CVE-2016-0648, CVE-2016-0649, CVE-2016-0650, CVE-2016-0651, CVE-2016-0655, CVE-2016-0666, CVE-2016-0668)
• Multiple flaws were found in the way PCRE handled malformed regular expressions. An attacker able to make MariaDB execute an SQL query with a specially crafted regular expression could use these flaws to cause it to crash or, possibly, execute arbitrary code. (CVE-2015-3210, CVE-2015-3217, CVE-2015-5073, CVE-2015-8381, CVE-2015-8383, CVE-2015-8384, CVE-2015-8385, CVE-2015-8386, CVE-2015-8388, CVE-2015-8391, CVE-2015-8392, CVE-2015-8395, CVE-2016-1283, CVE-2016-3191)
