upstream patch from git

The upstream patch is sufficiently different from Tavis' original patch that we should backport it instead.  This is a patch of the four git commits with the changelog changes removed.
Comment 13 Tomas Hoger 2009-04-17 06:53:13 UTC 
CVE-2009-0946:
Multiple integer overflows in FreeType 2.3.9 and earlier allow remote
attackers to execute arbitrary code via vectors related to large
values in certain inputs in (1) smooth/ftsmooth.c, (2) sfnt/ttcmap.c,
and (3) cff/cffload.c.

Comment 18 Tomas Hoger 2009-05-26 08:39:31 UTC 
There is no fixed upstream version yet.  Issue affects latest upstream version 2.3.9, new version with fixes from git (comment #7) has not been released yet.
Comment 20 Vincent Danen 2009-12-04 19:19:26 UTC 
This was fixed upstream in 2.3.10 according to the changelog, but the site does not list this as a release to fix security issues.

This still affects Fedora 10, 11, and 12.  Fedora 12 has 2.3.11 in testing, which would correct the issue, but the current release is 2.3.9 for current Fedora 11 and 12, and 2.3.7 for Fedora 10.

It does not look as though Fedora has been patched for this, and it really should be.  Behdad, can you take care of this please?
Comment 23 Vincent Danen 2009-12-10 15:50:49 UTC 
Fedora 12 currently has freetype-2.3.11-3.fc12 (FEDORA-2009-12629) so this issue has been corrected there.
