Overview
Affected versions of this package are vulnerable to Double Free in ff_nvdec_start_frame_sep_ref in libavcodec/nvdec.c. An attacker can corrupt memory by supplying a crafted video file that drives NVDEC decoding into the “No decoder surfaces left” error path, where the frame-description context is freed there and then freed again by the caller. This affects FFmpeg-based applications that use NVDEC hardware-accelerated decoding. The result is memory corruption during video decoding, which can crash the application and may be exploitable beyond a denial of service depending on the process and allocator state.
