Linux Distros Unpatched Vulnerability : CVE-2016-2047

medium Nessus Plugin ID 219337

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- The ssl_verify_server_cert function in sql-common/client.c in MariaDB before 5.5.47, 10.0.x before 10.0.23, and 10.1.x before 10.1.10; Oracle MySQL 5.5.48 and earlier, 5.6.29 and earlier, and 5.7.11 and earlier; and Percona Server do not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the- middle attackers to spoof SSL servers via a /CN= string in a field in a certificate, as demonstrated by /OU=/CN=bar.com/CN=foo.com. (CVE-2016-2047)

Note that Nessus relies on the presence of the package as reported by the vendor.
