--- Comment #4 from Tomas Hoger <thoger at 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.
