--- Comment #4 from Tomas Hoger thoger@redhat.com --- Upstream bug is: https://savannah.nongnu.org/bugs/?43590
Issue was fixed upstream in 2.5.4.
The issue is an integer overflow flaw in a check protecting against out-of-bounds reads, making it possible to bypass check. Crashing freetype using a specially-crafted font file should be possible because of this.
