This issue has been assigned the CVE name CVE-2009-0946
Created attachment 339698 [details] 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.
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.

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.
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?
Fedora 12 currently has freetype-2.3.11-3.fc12 (FEDORA-2009-12629) so this issue has been corrected there.
