Detailsinfo

A vulnerability, which was classified as critical, was found in libaom up to 3.8.x. Affected is the function img_alloc_helper. The manipulation with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at issues.chromium.org. This vulnerability is traded as CVE-2024-5171 since 05/21/2024. The exploitability is told to be easy. Technical details are known, but there is no available exploit.
