Revisions

May 15, 2018: Added language to notify users that an exploit for CVE-2018-4990
exists in the wild, and that proof-of-concept code for CVE-2018-4985 has been
published and is publicly available. Also added CVE-2018-4995 to replace
CVE-2018-4994, which was already assigned to an unrelated vulnerability in
Adobe Connect. Finally, added CVE-2018-4996 to replace CVE-2018-4946, which was
already assigned to an unrelated vulnerability in Adobe Photoshop.

May 16, 2018: Corrected the summary section by replacing CVE-2018-4985 with
CVE-2018-4993.  Proof-of-concept code is publicly available for CVE-2018-4993,
and not CVE-2018-4985.
