Ubuntu 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : qt4-x11 vulnerabilities (USN-1723-1)

Medium Nessus Plugin ID 64638


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


Richard J. Moore and Peter Hartmann discovered that Qt allowed redirecting requests from http to file schemes. If an attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. This issue only affected Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2012-5624)

Stephen Cheng discovered that Qt may report incorrect errors when ssl certificate verification fails. (CVE-2012-6093)

Tim Brown and Mark Lowe discovered that Qt incorrectly used weak permissions on shared memory segments. A local attacker could use this issue to view sensitive information, or modify program data belonging to other users. (CVE-2013-0254).

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-core and / or libqt4-network packages.
