[KB7442] Solution for ESET Endpoint product 5.x

Issue

We would like to inform you that we have identified an issue in older versions of the product of our Windows business products.

Details

ESET has identified that our kernel has a problem with verification of the timestamp of an already expired certificate (expired by 7^th Feb 2020). This method fails and our modules in older, legacy versions, are declared as untrusted and therefore are not loaded. This mechanism ensures that no untrusted library is loaded.

As a result, the affected versions fail to load modules (Firewall, HIPS, Updated, Device Control, Web and Email protection) and are not functional, therefore the protection is not functional.

Solution

Important!

If you are using affected versions and issue is not manifesting, do not restart the machine and perform upgrade immediately.
