Kerentanan Stack-based Buffer Overflow. Skor CVSS 3.1 7.8 (High) menurut vulncheck.com.

Deskripsi (NVD)

FFmpeg before commit 9d786e4 contains a stack buffer overflow in the MPEG-PS muxer (libavformat/mpegenc.c). When muxing input with more streams than the muxer's fixed-size stack buffer accommodates, the buffer is overflowed. A crafted input with an excessive number of streams triggers the overflow during MPEG-PS muxing.
