Comment 3 Marek Kašík 2015-09-11 14:51:50 UTC
It seems to me that this is already fixed in all maintained versions of Fedora. Check it please.

Comment 4 Huzaifa S. Sidhpurwala 2015-09-14 05:49:47 UTC
Upstream freetype git suggests that this issue was addressed in freetype-2.5.3.

Therefore this issue is already fixed in all the maintained versions of Fedora.

Comment 6 Adam Mariš 2015-09-29 09:18:52 UTC
CVE-2014-9746 is for accessing uninitialized memory issues
CVE-2014-9747 is for the fix for CWE-372 ("Incomplete Internal State Distinction") issue in the sense that the possibility of immediates-only mode isn't checked (in t42parse.c)
