Oracle MySQL 5.6.x < 5.6.28 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 5.6.x prior to 5.6.28 and is affected by multiple issues :

- Multiple unspecified flaws exists in the Server:DML subcomponent that allows an authenticated, remote attacker to cause a denial of service. (CVE-2016-0503, CVE-2016-0504, CVE-2016-0595, CVE-2016-0596) - An unspecified flaw exists in the Server:Options subcomponent that allows an authenticated, remote attacker to cause a denial of service. (CVE-2016-0505) - An unspecified flaw exists in the Client subcomponent that allows a local attacker to gain elevated privileges. (CVE-2016-0546) - Multiple unspecified flaws exist in the Server:Optimizer subcomponent that allow an authenticated, remote attacker to cause a denial of service. (CVE-2016-0597, CVE-2016-0598, CVE-2016-0611) - An unspecified flaw exists in the Server:InnoDB subcomponent that allows an authenticated, remote attacker to cause a denial of service. (CVE-2016-0600, CVE-2016-0610) - An unspecified flaw exists in the Server:Security:Encryption subcomponent that allows an authenticated, remote attacker to impact integrity. (CVE-2016-0606, CVE-2016-0609) - An unspecified flaw exists in the Server:Replication subcomponent that allows an authenticated, remote attacker to cause a denial of service. (CVE-2016-0607) - An unspecified flaw exists in the Server:UDF subcomponent that allows an authenticated, remote attacker to cause a denial of service. (CVE-2016-0608) - A denial of service vulnerability exists due to repeatedly executing a prepared statement when the default database has been changed. An authenticated, remote attacker can exploit this to cause the server to exit. (OSVDB 131599) - A denial of service vulnerability exists due to a flaw that is triggered when selecting DECIMAL values into user-defined variables. An authenticated, remote attacker can exploit this to cause the server to exit. (OSVDB 131601) - A flaw exists in the Server:InnoDB subcomponent due to a failure to check for destination files with the same name when using the ALTER TABLE operation to convert a table to an InnoDB file-per-table tablespace. An authenticated, remote attacker can exploit this to cause a denial of service. (OSVDB 131603) - A denial of service vulnerability exists that is triggered when updating views using ALL comparison operators on subqueries that select from indexed columns in the main table. An authenticated, remote attacker can exploit this to cause the server to exit, resulting in a denial of service condition. (OSVDB 131610) - A flaw exists in the Server:InnoDB subcomponent that is triggered when handling ALTER TABLE operations. An authenticated, remote attacker can exploit this to cause a denial of service condition. (OSVDB 131611) - A remote code execution vulnerability exists due to improper validation of user-supplied input to the 'strcpy()' and 'sprintf()' functions. An authenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (OSVDB 131612) - A denial of service vulnerability exists due to a flaw that is triggered when selecting DECIMAL values into user-defined variables. An authenticated, remote attacker can exploit this to cause the server to exit. (OSVDB 131613) - A denial of service vulnerability exists that is triggered when handling concurrent FLUSH PRIVILEGES and REVOKE or GRANT statements. An authenticated, remote attacker can exploit this to cause the server to exit by triggering an invalid memory access to proxy user information. (OSVDB 131614) - A denial of service vulnerability exists that is triggered on the second execution of a prepared statement where an ORDER BY clause references a column position. An authenticated, remote attacker can exploit this to cause the server to exit. (OSVDB 131615) - A denial of service vulnerability exists in the Server:Optimizer subcomponent due to accessing a stale pointer when handling filesorts for UPDATE statements. An authenticated, remote attacker can exploit this to cause the server to exit. (OSVDB 131616)

Solution

Upgrade to MySQL 5.6.28 or later.
