AOMedia v3.0.0 to v3.5.0 was discovered to contain an invalid read memory access via the component assign_frame_buffer_p in av1/common/av1_common_int.h.

Increasing the resolution of video frames, while performing a multi-threaded encode, can result in a heap overflow in av1_loop_restoration_dealloc().

Integer overflow in libaom internal function img_alloc_helper can lead to heap buffer overflow. This function can be reached via 3 callers: * Calling aom_img_alloc() with a large value of the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid. * Calling aom_img_wrap() with a large value of the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid. * Calling aom_img_alloc_with_border() with a large value of the d_w, d_h, align, size_align, or border parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid.

In libavif before 1.3.0, makeRoom in stream.c has an integer overflow and resultant buffer overflow in stream->offset+size.

In libavif before 1.3.0, avifImageRGBToYUV in reformat.c has integer overflows in multiplications involving rgbRowBytes, yRowBytes, uRowBytes, and vRowBytes.
