Re: Multiple bugs in freetype

[Josh Bressers <bressers () redhat com>]

I'm also adding a CVE id for the buffer overflows in the freetype demo programs:

CVE-2010-2527
http://savannah.nongnu.org/bugs/index.php?30054

The fix is here:
http://git.savannah.gnu.org/cgit/freetype/freetype2-demos.git/commit/?id=b995299b73ba4cd259f221f500d4e63095508bec

Thanks.
