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

High Nessus Plugin ID 59957


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


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.


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