HighMetricsAV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
FFmpeg through 9.0.2 contains a heap buffer overflow vulnerability in libavcodec/lcevcdec.c because LCEVC output picture dimensions are not validated against the allocated frame. Attackers can embed crafted LCEVC enhancement data with differing global configurations in H.264 or HEVC streams to corrupt heap memory in decoding applications.
