Описание
FFmpeg versions 3.4 through 8.1.2 contain an out-of-bounds write vulnerability in the vf_floodfill video filter that allows attackers to corrupt heap memory by supplying a dynamically sized video stream with filtergraph reinitialization disabled via -reinit_filter 0. When config_input() allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, filter_frame() performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening.
A flaw was found in FFmpeg. This vulnerability, an out-of-bounds write, affects the vf_floodfill video filter. An attacker could exploit this by providing a malicious video stream, which, when processed with filtergraph reinitialization disabled, causes heap memory corruption. This can lead to a denial of service due to a process crash, and in some cases, may enable arbitrary code execution.
Отчет
Red Hat Enterprise Linux has multiple layers of heap protection. NX/DEP (Non-Executable Memory) prevents code execution from heap, thus mitigating the code execution part of the exploit.
