MySQL 5.6.x < 5.6.29 Multiple DoS

medium Nessus Network Monitor Plugin ID 9238

Synopsis

The remote database server is vulnerable to multiple Denial of Service (DoS) attack vectors.

Description

The version of MySQL running on the remote host is 5.6.x prior to 5.6.29. It is, therefore, affected by multiple vulnerabilities :
 - A NULL pointer dereference flaw exists in the bundled version of OpenSSL in file rsa_ameth.c due to improper handling of ASN.1 signatures that are missing the PSS parameter. A remote attacker can exploit this to cause the signature verification routine to crash, resulting in a denial of service condition. (CVE-2015-3194)
 - An unspecified flaw exists in the DML subcomponent that allows an authenticated, remote attacker to impact integrity and availability. (CVE-2016-0640)
 - An unspecified flaw exists in the MyISAM subcomponent that allows an authenticated, remote attacker to disclose sensitive information or cause a denial of service condition. (CVE-2016-0641)
 - An unspecified flaw exists in the DDL subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0644)
 - An unspecified flaw exists in the DML subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0646)
 - An unspecified flaw exists in the PS subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0649)
 - An unspecified flaw exists in the Replication subcomponent that allows an authenticated, remote attacker to cause a denial of service condition.(CVE-2016-0650)
 - An unspecified flaw exists in the Options subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0661)
 - An unspecified flaw exists in the Security: Encryption subcomponent that allows an authenticated, remote attacker to cause a denial of service condition.(CVE-2016-0665)
 - An unspecified flaw exists in the InnoDB subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-0668)
 - A denial of service vulnerability exists in the bundled OpenSSL library due to improper handling of variables declared as TEXT or BLOB. An authenticated, remote attacker can exploit this to corrupt data or cause a denial of service condition.
 - A denial of service vulnerability exists that is triggered when handling a 'CREATE TEMPORARY TABLE ..SELECT' statement involving BIT columns. An authenticated, remote attacker can exploit this to create an improper table or cause the server to exit, resulting in a denial of service condition.
 - A denial of service vulnerability exists due to an unspecified flaw in LOCK TABLES that is triggered when opening a temporary MERGE table consisting of a view in the list of tables. An authenticated, remote attacker can exploit this to cause the server to exit, resulting in a denial of service condition.
 - A denial of service vulnerability exists due to a flaw that is triggered when repeatedly executing 'ALTER TABLE v1 CHECK PARTITION' as a prepared statement. An authenticated, remote attacker can exploit this to cause the server to exit, resulting in a denial of service condition.

Solution

Upgrade to MySQL 5.6.29 or later.
