[KB7442] Solution for ESET Endpoint product 5.x

Issue

Details

ESET has identified that our kernel has a problem with verification of the timestamp of an already expired certificate (expired by 7th Feb 2020). This method fails and our modules in older, legacy versions, are declared as untrusted and 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, and the protection is not functional.
