Ubuntu 10.04 LTS / 11.04 : qt4-x11 vulnerabilities (USN-1504-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected libqt4-network and / or libqtgui4 packages.

Risk factor :

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.7
(CVSS2#E:F/RL:OF/RC:C)
