    Package        : firefox-esr
    CVE ID         : CVE-2018-12376 CVE-2018-12377 CVE-2018-12378
    
    Several security issues have been found in the Mozilla Firefox web
    browser: Multiple memory safety errors and use-after-frees may lead to
    the execution of arbitrary code or denial of service.
    
    Debian follows the extended support releases (ESR) of Firefox. Support
    for the 52.x series has ended, so starting with this update we're now
    following the 60.x releases.
    
    Between 52.x and 60.x, Firefox has undergone significant internal
    updates, which makes it incompatible with a number of extensions. For
    more information please refer to
    https://www.mozilla.org/en-US/firefox/60.0esr/releasenotes/ 
    
    In addition, the new Firefox packages require Rust to build. A
    compatible Rust toolchain has been backported to Debian stretch, but is
    not available for all architectures which previously supported the
    purely C++-based Firefox packages. Thus, the new Firefox packages
    don't support the armel, armhf, mips, mips64el and mipsel architectures
    at this point.
    
    For the stable distribution (stretch), these problems have been fixed in
    version 60.2.0esr-1~deb9u2.
    
    We recommend that you upgrade your firefox-esr packages.
