Reason and background of this blog
This blog contains information about vulnerabilities, the possible risk and advice on how to prevent or limit damage. Below are the possible risks, details and background information.
Below CVE numbers were linked to the vulnerabilities in August 2020:
Patches were quickly released and are still available for users who have not yet upgraded the software.
By using these vulnerabilities, an attacker can increase their rights on the system (privilege escalation). This makes it possible to make use of system resources that would not be available to the attacker under normal circumstances.
To exploit these vulnerabilities, an attacker must already have access to the system, either locally or remotely.
Below versions/products are vulnerable:
|Versions prior to patch 3 b8378||Windows|
|Versions prior to macOS Patch 1||macOS|
|Versions prior to Aug 2020 Monthly Patch
|OfficeScan||Versions prior to XG SP1 CP5698||Windows|
Considering that updates have been available for these vulnerabilities since August last year, the applications should already be patched. In case your systems have not been patched, please update as soon as possible.
