Marc Schoenefeld discovered that Pango incorrectly handled certain
Glyph Definition (GDEF) tables. If a user were tricked into displaying

Dan Rosenberg discovered that Pango incorrectly handled certain
FT_Bitmap objects. If a user were tricked into displaying text with a
specially- crafted font, an attacker could cause a denial of service
or execute arbitrary code with privileges of the user invoking the

reduce the vulnerability to a denial of service. (CVE-2011-0020)
