Updated phpmyadmin packages fix security vulnerability
In phpMyAdmin before 4.4.15.8, the decryption of the username/password is vulnerable to a padding oracle attack. The can allow an attacker who has access to a user's browser cookie file to decrypt the username and password. Also, the same initialization vector (IV) is used to hash the username and password stored in the phpMyAdmin cookie. If a user has the same password as their username, an attacker who examines the browser cookie can see that they are the same (CVE-2016-6606).
In phpMyAdmin before 4.4.15.8, multiple vulnerabilities have been discovered in the following areas of phpMyAdmin: Zoom search, GIS editor, Relation view, several Transformations, XML export, MediaWiki export, Designer, when the MySQL server is running with a specially-crafted log_bin directive, Database tab, Replication feature, and Database search (CVE-2016-6607).
In phpMyAdmin before 4.4.15.8, a vulnerability was found where a specially crafted database name could be used to run arbitrary PHP commands through the array export feature (CVE-2016-6609).
In phpMyAdmin before 4.4.15.8, a full path disclosure vulnerability was discovered where a user can trigger a particular error in the export mechanism to discover the full path of phpMyAdmin on the disk (CVE-2016-6610).
In phpMyAdmin before 4.4.15.8, a vulnerability was reported where a specially crafted database and/or table name can be used to trigger an SQL injection attack through the export functionality (CVE-2016-6611).
In phpMyAdmin before 4.4.15.8, a vulnerability was discovered where a user can exploit the LOAD LOCAL INFILE functionality to expose files on the server to the database system (CVE-2016-6612).
In phpMyAdmin before 4.4.15.8, a vulnerability was found where a user can specially craft a symlink on disk, to a file which phpMyAdmin is permitted to read but the user is not, which phpMyAdmin will then expose to the user (CVE-2016-6613).
In phpMyAdmin before 4.4.15.8, a vulnerability was reported with the %u username replacement functionality of the SaveDir and UploadDir features. When the username substitution is configured, a specially-crafted user name can be used to circumvent restrictions to traverse the file system (CVE-2016-6614).
In phpMyAdmin before 4.4.15.8, multiple XSS vulnerabilities were found in the following areas: Navigation pane and database/table hiding feature, the "Tracking" feature, and GIS visualization feature (CVE-2016-6615).
In phpMyAdmin before 4.4.15.8, a vulnerability was discovered in the following features where a user can execute an SQL injection attack against the account of the control user: User group Designer (CVE-2016-6616).
In phpMyAdmin before 4.4.15.8, a vulnerability was found in the transformation feature allowing a user to trigger a denial-of-service (DOS) attack against the server (CVE-2016-6618).
In phpMyAdmin before 4.4.15.8, a vulnerability was discovered in the user interface preference feature where a user can execute an SQL injection attack against the account of the control user (CVE-2016-6619).
In phpMyAdmin before 4.4.15.8, a vulnerability was reported where some data is passed to the PHP unserialize() function without verification that it's valid serialized data. A malicious user may be able to manipulate the stored data in a way to result in code being loaded and executed (CVE-2016-6620).
In phpMyAdmin before 4.4.15.8, a vulnerability was discovered where an unauthenticated user is able to execute a denial-of-service (DOS) attack by forcing persistent connections when phpMyAdmin is running with $cfg['AllowArbitraryServer']=true; (CVE-2016-6622).
In phpMyAdmin before 4.4.15.8, a vulnerability has been reported where a malicious authorized user can cause a denial-of-service (DOS) attack on a server by passing large values to a loop (CVE-2016-6623).
In phpMyAdmin before 4.4.15.8, a vulnerability was discovered where, under certain circumstances, it may be possible to circumvent the phpMyAdmin IP-based authentication…
