Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 45.7.0 ESR.

Security Fix(es):

  • Multiple flaws were found in the processing of malformed web content. A web
    page containing malicious content could cause Firefox to crash or, potentially,
    execute arbitrary code with the privileges of the user running Firefox.
    (CVE-2017-5373, CVE-2017-5375, CVE-2017-5376, CVE-2017-5378, CVE-2017-5380,
    CVE-2017-5383, CVE-2017-5386, CVE-2017-5390, CVE-2017-5396)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Jann Horn, Filipe Gomes, Muneaki Nishimura, Nils, Armin
Razmjou, Christian Holler, Gary Kwong, Andre Bargull, Jan de Mooij, Tom
