Description

It was discovered that Qt did not properly handle wildcard domain
names or IP addresses in the Common Name field of X.509 certificates.
An attacker could exploit this to perform a man in the middle attack
to view sensitive information or alter encrypted communications. This
issue only affected Ubuntu 10.04 LTS. (CVE-2010-5076)

A heap-based buffer overflow was discovered in the HarfBuzz module.
If a user were tricked into opening a crafted font file in a Qt
application, an attacker could cause a denial of service or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2011-3193)

It was discovered that Qt did not properly handle greyscale TIFF
images. If a Qt application could be made to process a crafted TIFF
file, an attacker could cause a denial of service. (CVE-2011-3194)
