CVE-2022-41847

Denial of service via unreleased memory

Published Sep 30, 2022 · Updated May 20, 2025

A memory leak in Bento4 1.6.0-639 allows local users to cause a denial of service by processing a crafted media file. The AP4_StdcFileByteStream::Create function fails to release allocated memory during file-byte-stream creation, allowing repeated processing to exhaust available memory. Exploitation requires local access and user interaction with a crafted file; the bounded impact is service interruption without confidentiality or integrity loss.
