Details

Marc Schoenefeld discovered that Pango incorrectly handled certain Glyph
Definition (GDEF) tables. If a user were tricked into displaying text with
a specially-crafted font, an attacker could cause Pango to crash, resulting
in a denial of service. This issue only affected Ubuntu 8.04 LTS and 9.10.
(CVE-2010-0421)

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 program. The
default compiler options for affected releases should reduce the
vulnerability to a denial of service. (CVE-2011-0020)

It was discovered that Pango incorrectly handled certain memory
reallocation failures. If a user were tricked into displaying text in a way
that would cause a reallocation failure, an attacker could cause a denial
of service or execute arbitrary code with privileges of the user invoking
the program. This issue only affected Ubuntu 9.10, 10.04 LTS and 10.10.
(CVE-2011-0064)
