Vulnerability in ESET products, upgrade immediately

An analysis of the code emulator feature it uses in the της ESET (εξομοιωτής κώδικα) έδειξε ότι δεν ήταν αρκετά ισχυρό και ότι μπορεί να παραβιαστεί εύκολα, επιτρέποντας σε έναν εισβολέα να πάρει τον πλήρη έλεγχο ενός συστήματος που τρέχει την ευάλωτη λύση ασφαλείας.it nods

The code emulator is integrated into the company's antivirus products and allows to run files or scipts before the user does it. This process occurs in a secluded environment and so the actual system can not be affected.

Data collected is provided to the heuristic software analyst, who decides whether their nature is malicious or suspect.

Researcher Tavis Ormandy from ανακάλυψε την ευπάθεια στο NOD32 Antivirus, αλλά όπως αναφέρει επηρεάζονται και άλλα προϊόντα, σε όλες τις εκδόσεις (Windows, OS X και Linux), καθώς και οι εκδόσεις Endpoint και Business.

Ormandy found the glitch, analyzed it and created a remote root exploit in a few days, indicating that it can obtain full access to the victim's system.

But let's say that Ormandy declared vulnerability to ESET at 18 in June, and the company immediately released an update for the scan engine (just 4 days later).
