Avira » Antivirus : Security Vulnerabilities, CVEs, (Denial of service)

A vulnerability within the Avira network protection feature allowed an attacker with local execution rights to cause an overflow. This could corrupt the data on the heap and lead to a denial-of-service situation. Issue was fixed with Endpointprotection.exe version 1.0.2303.633

Avira Antivirus before 5.0.2003.1821 on Windows allows privilege escalation or a denial of service via abuse of a symlink.
