Several 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, denial of service or domain spoofing.
 
Debian follows the extended support releases (ESR) of Firefox. Support
for the 45.x series has ended, so starting with this update we're now
following the 52.x releases.

For the stable distribution (jessie), these problems have been fixed in
version 52.2.0esr-1~deb8u1.

For the upcoming stable distribution (stretch), these problems will be
fixed soon.

For the unstable distribution (sid), these problems have been fixed in
version 52.2.0esr-1.

We recommend that you upgrade your firefox-esr packages.
