Detailsinfo

A vulnerability has been found in KDE kdelibs and classified as critical. Affected by this vulnerability is an unknown code block of the component Access Restriction. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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."
