Title: FreeType vulnerabilities
Summary: FreeType vulnerabilities
Several integer overflows have been discovered in the FreeType

CVE-2006-0747 Freetype integer underflow (CVE-2006-2661)
Freetype integer underflow
While fuzzing some pdf files a few weeks back, I ended up finding an
integer underflow in freetype2. Upstream did commit some fixes, so
this issue is somewhat public.
1.ttf will generate this error.
Patches:
http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/pshinter/pshglob.c?r1=1.30&r2=1.31&makepatch=1&diff_format=h

http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/type1/t1load.c?r1=1.104&r2=1.105&makepatch=1&diff_format=h
The problem is the number of blue values needs to be even. If a font
file claims it's odd, freetype2 doesn't handle it well.
