## Technical details

A heap buffer out-of-bounds read vulnerability exists in the Avira Antivirus engine across Windows, macOS, and Linux platforms. The flaw is triggered when the engine attempts to scan a specially crafted, malformed Windows Portable Executable (PE) file. An attacker can exploit this by inducing the engine to process such a file, which may result in a denial-of-service (crashing the antivirus process) or arbitrary code execution in the context of the scanning engine. The vulnerability is addressed in engine builds 8.3.70.98 and later.
