This issue DOES NOT affect the latest versions of our products including the latest ESET Endpoint Antivirus/ESET Endpoint Security – 6.6.2089, 7.2 and 7.3 and ESET File Security for Windows 7.1.12008 and customers using the latest versions are not affected in any way. This issue is relevant to the impacted versions listed and described above. The newest versions of our products are NOT affected.

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 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.

Symptoms

For versions older than 5.0.2271.x symptoms are:

  • Failed loading of modules for v5 family
  • GUI of the main window is in English and the logo shows ESET Smart Security 5 instead of Endpoint Security

For versions 6.5.x symptoms are:

  • Product reports "Anti-Phishing protection is non-functional"
  • Product reports that it is not activated
  • Product’s advanced settings have features missing

If they are managed by our ESET Remote Administrator or ESET Security Management Center, they will fall back to the respective parametric group and report an alert as not being activated and the antiphishing module as not functional.
