USN-3761-1 fixed vulnerabilities in Firefox. The update caused several
regressions affecting spellchecker dictionaries and search engines, which
were partially fixed by USN-3761-2. This update contains the remaining fix.
We apologize for the inconvenience.
Original advisory details:
Multiple security issues were discovered in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, or execute
arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377,

CVE-2018-16863 ghostscript: incomplete fix for CVE-2018-16509
It was found that the fix for CVE-2018-16509 provided in Red Hat Enterprise Linux 7 was not sufficient.
Discussion:
The full fix for CVE-2018-16509 (bug 1619748) consists of the following 4 upstream patches:
http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=5516c614dc33
http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=78911a01b67d

http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=520bb0ea7519
The RHSA-2018:2918 erratum for Red Hat Enterprise Linux 7 only included the first 2 fixes, and hence failed to fix CVE-2018-16509 completely.
