Security database references:
In Mitre's CVE dictionary: CVE-2018-19788, CVE-2019-6133.
More information:

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.
