3. Description:

Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 52.6.0 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-2018-5089, CVE-2018-5091, CVE-2018-5095, CVE-2018-5096,
CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5102, CVE-2018-5103,
CVE-2018-5104, CVE-2018-5117)

* To mitigate timing-based side-channel attacks similar to "Spectre" and
"Meltdown", the resolution of performance.now() has been reduced from 5I1/4s
to 20I1/4s.

Red Hat would like to thank the Mozilla project for reporting these issues.
