Technical details
This vulnerability is a reachable assertion in the gf_node_get_field_count function within scenegraph/base_scenegraph.c of the MP4Box component. The issue is triggered by local manipulation of input data—an attacker can craft a specially-formed media file that causes the assertion to fail. The vulnerability requires local file access and does not require authentication. A successful exploit results in application termination (denial of service). The issue has been patched in version abi-16.23 (commit 49dee5cad329cfed310c1682703df7daa47df31a).
