Technical details
A NULL pointer dereference (CWE-476) exists in the Avira Antivirus engine across Windows, macOS, and Linux platforms. The vulnerability is triggered when the engine attempts to parse a malformed Windows Portable Executable (PE) file during a scan. An attacker can exploit this by providing a crafted PE file that, when processed, causes the antivirus engine process to crash (Denial-of-Service). The attack requires the file to be scanned, typically involving some level of user interaction or automated system activity. The issue is resolved in engine builds 8.3.70.64 and later.
