Debian: DSA-3831-1 moderate: firefox-esr memory safety threat

Multiple security issues have been found in the Mozilla Firefox web
browser: Multiple memory safety errors, use-after-frees, buffer
overflows and other implementation errors may lead to the execution of
arbitrary code, information disclosure or denial of service.

For the stable distribution (jessie), these problems have been fixed in
version 45.9.0esr-1~deb8u1.

For the unstable distribution (sid), these problems have been fixed in
version 45.9.0esr-1.

We recommend that you upgrade your firefox-esr packages.
