MySQL 5.5.x < 5.5.53 Multiple Vulnerabilities (October 2016 CPU)
Critical Nessus Plugin ID 94196
Synopsis
The remote database server is affected by multiple vulnerabilities.
Description
The version of MySQL running on the remote host is 5.5.x prior to 5.5.53. It is, therefore, affected by multiple vulnerabilities :
- An unspecified flaw exists in the Optimizer subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-3492)
- An unspecified flaw exists in the Security: Encryption subcomponent that allows an authenticated, remote attacker to disclose sensitive information.
(CVE-2016-5584)
- An unspecified flaw exists in the MyISAM subcomponent that allows a local attacker to gain elevated privileges. (CVE-2016-5616)
- An unspecified flaw exists in the Error Handling subcomponent that allows a local attacker to gain elevated privileges. (CVE-2016-5617)
- An unspecified flaw exists in the GIS subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-5626)
- An unspecified flaw exists in the Federated subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2016-5629)
- A flaw exists in the check_log_path() function within file sql/sys_vars.cc due to inadequate restrictions on the ability to write to the my.cnf configuration file and allowing the loading of configuration files from path locations not used by current versions. An authenticated, remote attacker can exploit this issue by using specially crafted queries that utilize logging functionality to create new files or append custom content to existing files. This allows the attacker to gain root privileges by inserting a custom .cnf file with a 'malloc_lib=' directive pointing to specially crafted mysql_hookandroot_lib.so file and thereby cause MySQL to load a malicious library the next time it is started. (CVE-2016-6662)
- 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.
(CVE-2016-7440)
- An unspecified flaw exists in the Types subcomponent that allows an authenticated, remote attacker to cause a denial of service condition.(CVE-2016-8283)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to MySQL version 5.5.53 or later.
