Understand Mageia 2024-0220: Safeguarding Against AOM Integer Overflow Vulnerability
Summary
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. (CVE-2024-5171)
