CVE-2014-5033 – polkit-qt: insecure calling of polkit

https://notcve.org/view.php?id=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." KDE kdelibs anterior a 4.14 y kauth anterior a 5.1 no utilizan debidamente D-Bus para la comunicación con una autoridad polkit, lo que permite a usuarios locales evadir las restricciones de acceso mediante el aprovechamiento de una condición de carrera PolkitUnixProcess PolkitSubject a través de un proceso (1) setuid o (2) pkexec, relacionado con el CVE-2013-4288 y 'condiciones de carrera de reuso PID.' It was found that polkit-qt handled authorization requests with PolicyKit via a D-Bus API that is vulnerable to a race condition. A local user could use this flaw to bypass intended PolicyKit authorizations. • http://lists.opensuse.org/opensuse-updates/2014-08/msg00012.html http://quickgit.kde.org/?p=kauth.git&a=commit&h=341b7d84b6d9c03cf56905cb277b47e11c81482a http://quickgit.kde.org/?p=kdelibs.git&a=commitdiff&h=e4e7b53b71e2659adaf52691d4accc3594203b23 http://rhn.redhat.com/errata/RHSA-2014-1359.html http://secunia.com/advisories/60385 http://secunia.com/advisories/60633 http://secunia.com/advisories/60654 http://www.debian.org/security/2014/dsa-3004 http://www.kde.org/info/security/advisory-201407 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
