08 May 2020 — Avira Free Antivirus through 15.0.2005.1866 allows local users to discover user credentials.

09 Apr 2020 — An issue was discovered in Avira Free-Antivirus before 15.0.2004.1825. The Self-Protection feature does not prohibit a write operation from an external process. Thus, code injection can be used to turn off this feature. After that, one can construct an event that will modify a file at a specific location, and pass this event to the driver, thereby defeating the anti-virus functionality. Se detectó un problema en Avira Free-Antivirus versiones anteriores a 15.0.2004.1825. • https://support.avira.com/hc/en-us/articles/360000109798-Avira-Antivirus-for-Windows •

21 Mar 2017 — Code injection vulnerability in Avast Premier 12.3 (and earlier), Internet Security 12.3 (and earlier), Pro Antivirus 12.3 (and earlier), and Free Antivirus 12.3 (and earlier) allows a local attacker to bypass a self-protection mechanism, inject arbitrary code, and take full control of any Avast process via a "DoubleAgent" attack. One perspective on this issue is that (1) these products do not use the Protected Processes feature, and therefore an attacker can enter an arbitrary Application Verifier Provider... • http://cybellum.com/doubleagent-taking-full-control-antivirus • CWE-427: Uncontrolled Search Path Element •
