Description Laura Pardo 2018-08-07 20:24:53 UTC 
A flaw was found in Pango since versions 1.40.8 up to newer. Typing certain invalid Emoji sequences into a GTK+ application can trigger a Reachable  Assertion resulting in an application crash.
Comment 1 Stefan Cornelius 2018-08-08 12:49:18 UTC 
Statement:

This issue did not affect the versions of pango as shipped with Red Hat Enterprise Linux 5, 6, and 7 as they did not include support for emojis.
