Descriptions

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.

YoruFukurou (NightOwl) en versiones anteriores a 2.85 confía en soporte para modificadores emoji skin-tone a pesar de que este soporte no se encuentra en CoreText CTFramesetter API en OS X 10.9, lo que permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de una secuencia de caracteres emoji manipulada.
