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 5.5.54. 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-2017-3238)
- An unspecified flaw exists in the Charsets subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3243)
- An unspecified flaw exists in the DML subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3244)
- An unspecified flaw exists in the DDL subcomponent that allows an authenticated, remote attacker to cause a denial of service condition. (CVE-2017-3258)
- An unspecified flaw exists in the Packaging subcomponent that allows a local attacker to impact confidentiality and availability. (CVE-2017-3265)
- Multiple unspecified flaws exist in the Packaging subcomponent that allow a local attacker to gain elevated privileges. (CVE-2017-3291, CVE-2017-3312)
- An unspecified flaw exists in the MyISAM subcomponent that allows a local attacker to disclose sensitive information. (CVE-2017-3313)
- An unspecified flaw exists in the Logging subcomponent that allows a local attacker to cause a denial of service condition. (CVE-2017-3317)
- An unspecified flaw exists in the Error Handling subcomponent that allows a local attacker to disclose sensitive information. (CVE-2017-3318)
- A local privilege escalation vulnerability exists in the mysqld_safe component due to unsafe use of the 'rm' and 'chown' commands. A local attacker can exploit this to gain elevated privileges.
- An unspecified flaw exists in the mysqld_safe component that allows an authenticated, remote attacker to have an unspecified impact.
- An overflow condition exists in the Optimizer component due to improper validation of user-supplied input when handling nested expressions. An authenticated, remote attacker can exploit this to cause a stack-based buffer overflow, resulting in a denial of service condition.
- An unspecified flaw exists when handling a CREATE TABLE query with a DATA DIRECTORY clause. An authenticated, remote attacker can exploit this to gain elevated privileges.
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 5.5.54 or later.
