Debian DLA-1644-1 : policykit-1 security update

high Nessus Plugin ID 121423

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
