Description

YoruFukurou (NightOwl) before 2.85 relies on support for emoji skin-tone modifiers even though this support is missing from the CoreText CTFramesetter API on OS X 10.9, which allows remote attackers to cause a denial of service (application crash) via a crafted emoji character sequence.
