Description:Summary:
The remote host is missing an update for the Debian 'policykit-1' package(s) announced via the DLA-1644-1 advisory.

Vulnerability Insight:
Two vulnerabilities were found in Policykit, a framework for managing administrative policies and privileges:

CVE-2018-19788

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.
