phpmyadmin - security update

Phpmyadmin, a web administration tool for MySQL, had several
vulnerabilities reported.

• CVE-2016-6606
  A pair of vulnerabilities were found affecting the way cookies are
  stored.

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.

A vulnerability was found where the same initialization vector
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 — but the attacker can not directly decode these values from
the cookie as it is still hashed.

• CVE-2016-6607
  Cross site scripting vulnerability in the replication feature
• CVE-2016-6609
  A specially crafted database name could be used to run arbitrary PHP
  commands through the array export feature.
• CVE-2016-6611
  A specially crafted database and/or table name can be used to trigger
  an SQL injection attack through the SQL export functionality.
• CVE-2016-6612
  A user can exploit the LOAD LOCAL INFILE functionality to expose
  files on the server to the database system.
• CVE-2016-6613
  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-2016-6614
  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-2016-6620
  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.
• CVE-2016-6622
  An unauthenticated user is able to execute a denial-of-service
  attack by forcing persistent connections when phpMyAdmin is running
  with $cfg[‘AllowArbitraryServer’]=true;.
• CVE-2016-6623
  A malicious authorized user can cause a denial-of-service attack
  on a server by passing large values to a loop.
• CVE-2016-6624
  A vulnerability was discovered where, under certain circumstances,
  it may be possible to circumvent the phpMyAdmin IP-based
  authentication rules.
  When phpMyAdmin is used with IPv6 in a proxy server environment,
  and the proxy server is in the allowed range but the attacking
  computer is not allowed, this vulnerability can allow the attacking
  computer to connect despite the IP rules.
• CVE-2016-6630
  An authenticated user can trigger a denial-of-service attack by
  entering a very long password at the change password dialog.
• CVE-2016-6631
  A vulnerability was discovered where a user can execute a remote
  code execution attack against a server when phpMyAdmin is being
  run as a CGI application. Under certain server configurations,
  a user can pass a query string which is executed as a
  command-line argument by shell scripts.

For Debian 7 Wheezy, these problems have been fixed in version
3.4.11.1-2+deb7u6.

We recommend that you upgrade your phpmyadmin packages.
