firefox-esr - security update

Multiple security issues have been found in the Mozilla Firefox web
browser: Multiple memory safety errors, buffer overflows and other
implementation errors may lead to the execution of arbitrary code,
cross-site scriping, information disclosure and bypass of the
same-origin policy.

For Debian 7 Wheezy, these problems have been fixed in version
45.3.0esr-1~deb7u1.

We recommend that you upgrade your firefox-esr packages.
