**Name of the Vulnerable Software and Affected Versions**
YoruFukurou (NightOwl) versions prior to 2.85
**Description**
The issue allows remote attackers to cause a denial of service, resulting in an application crash, via a crafted emoji character sequence. This is because YoruFukurou relies on support for emoji skin-tone modifiers, which is missing from the CoreText CTFramesetter API on OS X 10.9.
**Recommendations**
For versions prior to 2.85, update to version 2.85 or later to resolve the issue.
