CVE-2010-3126: Untrusted search path vulnerability in avast!

Untrusted search path vulnerability in avast! Free Antivirus version 5.0.594 and earlier allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse mfc90loc.dll that is located in the same folder as an avast license (.avastlic) file.

Security readout for executives and security teams

This is a legacy avast! Free Antivirus issue where opening or handling an avast license file could cause avast to load a malicious DLL from the same folder. That could let an attacker run code on the affected machine. The provided sources do not show active exploitation or a named patch. Exposure is likely limited to organizations still running avast! Free Antivirus 5.0.594 or earlier, especially on Windows systems where users process license files from shared, downloaded, or email-delivered folders. Address when legacy Avast 5 is present. Business urgency is low for modern environments but higher for unmanaged or old endpoints because antivirus software has privileged trust and code execution impact. Mitigation focus: Identify and retire avast! Free Antivirus 5.0.594 or earlier.; Check Avast vendor guidance for supported upgrade or replacement paths.; Block use of untrusted .avastlic files on affected systems..
