## Technical details

A heap-based out-of-bounds read vulnerability exists in the Avira Antivirus engine (versions prior to 8.3.70.68) across Windows, macOS, and Linux platforms. The flaw is triggered when the engine parses a malformed PDF file during a scan operation. While primarily an out-of-bounds read, the advisory indicates this can be leveraged for either a Denial-of-Service (DoS) of the antivirus process or Local Code Execution (LCE). Exploitation requires a user to interact with a malicious file (UI:R), such as by downloading or opening a directory containing the malformed PDF that triggers an automatic scan. The issue is addressed in engine build 8.3.70.68 and later.
