CVE-2016-6620

First published: Sun Dec 11 2016(Updated: )

An issue was discovered in phpMyAdmin. Some data is passed to the PHP unserialize() function without verification that it's valid serialized data. The unserialization can result in code execution because of the interaction with object instantiation and autoloading. All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 4.4.15.8), and 4.0.x versions (prior to 4.0.10.17) are affected.
