Description :

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

user invoking the program. This issue only affected Ubuntu 9.10, 10.04
LTS and 10.10. (CVE-2011-0064).

Solution :

Update the affected packages.
