Unvalidated data passed to unserialize()
A vulnerability was reported where some data is passed to the PHP
unserialize() function without verification that it's valid serialized data.
Due to how the PHP function operates,
Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this.
Therefore, a malicious user may be able to manipulate the stored data in a way to exploit this weakness.
We consider this vulnerability to be moderately severe.
All 4.6.x versions (prior to 4.6.4), 4.4.x versions (prior to 22.214.171.124), and 4.0.x versions (prior to 126.96.36.199) are affected
Upgrade to phpMyAdmin 4.6.4, 188.8.131.52, or 184.108.40.206 or newer or apply patch listed below.
