[SECURITY] [DLA 708-1] mysql-5.5 security update

Package : mysql-5.5
Version : 5.5.53-0+deb7u1
CVE ID : CVE-2016-5584 CVE-2016-7440
Debian Bug : 841050

Several issues have been discovered in the MySQL database server. The
vulnerabilities are addressed by upgrading MySQL to the new upstream
version 5.5.53, which includes additional changes, such as performance
improvements, bug fixes, new features, and possibly incompatible
changes. Please see the MySQL 5.5 Release Notes and Oracle's Critical
Patch Update advisory for further details:

• https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-53.html
• http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html

Also note that packaging will now create /var/lib/mysql-files, as
server will now by default restrict all import/export operations to
this directory.This can be changed using the secure-file-priv
configuration option.

For Debian 7 "Wheezy", these problems have been fixed in version
5.5.53-0+deb7u1.

We recommend that you upgrade your mysql-5.5 packages.
