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 5μs
to 20μs.
Red Hat would like to thank the Mozilla project for reporting these issues.
