CVE-2014-5033

KDE kdelibs before 4.14 and kauth before 5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, related to CVE-2013-4288 and "PID reuse race conditions."

This update fixes a security vulnerability in the polkit authentication backend of kdelibs (CVE-2014-5033) (mga#13792), and fixes some additional issues:

• duplicate targets in PythonMacros.cmake (reviewboard kde 111371),
• kded4 leak sockets in NetworkInterface::isWireless() (bko#324954),
• media type application/x-konsole is unsupported (bko#292378),
• pure Qt applications (like VLC) that get the kdelibs file dialog are not properly translated (mga#12982),
• meinproc4 doesn't substitute entity with libxml2 fixed for CVE-2014-0191 (bko#335001, mga#13555, mga#13559),

This KDE 4 update provides an upgrade to the last stable version of KDE Applications and Development Platform for the 4.12 series, and updates Plasma Workspaces to 4.11.12.

KDE kdelibs before 4.14 and kauth before 5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, related to CVE-2013-4288 and "PID reuse race conditions."

It was discovered that kauth was using polkit in an unsafe manner. A local attacker could possibly use this issue to bypass intended polkit authorizations.
