Subject: [FFmpeg-devel] [PATCH] compat/android: fix DLL hijacking by using absolute paths
Date: Mon, 5 Jan 2026 01:35:03 +0100
Message-ID: <20260105003504.1895-4-monsterbat02@gmail.com> (raw)
In-Reply-To: <20260105003504.1895-1-monsterbat02@gmail.com>
Hardcode the path to libbinder_ndk.so to /system/lib64/ or /system/lib/ to prevent loading malicious libraries from unauthorized directories.
