Quick assessment

Affected
FFmpeg FFmpeg
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FFmpeg 9.0.2 及更早版本在 Motion Pixels 解码器中存在空指针解引用漏洞。该漏洞源于 函数忽略了 的失败返回值。攻击者可通过 libavcodec API 提交一个大小约为 2^28 字节的包，导致位计数溢出，进而引发对 NULL 缓冲区的读取，最终造成进程崩溃。

Vulnerability Title
FFmpeg through 9.0.2 NULL Pointer Dereference via Motion Pixels Decoder
Source: CVE Program / CVE List V5
Vulnerability Description
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in the Motion Pixels decoder because mp_decode_frame() ignores init_get_bits() failure. Attackers supplying a roughly 2^28-byte packet through the libavcodec API overflow the bit count, causing reads from a NULL buffer that crash the process.
