Debian: DSA-4466-1 Moderate: Firefox-Esr Type Confusion Risk

Samuel Gross discovered a type confusion bug in the JavaScript engine of
the Mozilla Firefox web browser, which could result in the execution of
arbitrary code when browsing a malicious website.

For the stable distribution (stretch), this problem has been fixed in
version 60.7.1esr-1~deb9u1.

We recommend that you upgrade your firefox-esr packages.
