Upgrade jxl-grid to version 0.6.2 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the AlignedGrid::with_alloc_tracker function due to unchecked multiplication of width and height, which can result in integer overflow on 32-bit platforms. An attacker can achieve arbitrary code execution by supplying a crafted image that causes the allocation of an undersized buffer, leading to out-of-bounds writes during image decoding. This is only exploitable if the code is running on a 32-bit platform and processes attacker-controlled image data.
