Summary

It was discovered that incorrect processing of very high UIDs in
Policykit could result in authentication bypass.

CVE-2019-6133

Jann Horn of Google found that Policykit doesn't properly check
if a process is already authenticated, which can lead to an
authentication reuse by a different user.

For Debian 8 "Jessie", these problems have been fixed in version
0.105-15~deb8u4.

We recommend that you upgrade your policykit-1 packages.
