The vulnerability of the `unpack_32bit()` function in software for storing OpenEXR images with a wide dynamic range of brightness levels allows a hacker to cause a service failure.

The vulnerability of the unpack32bit function in software for storing OpenEXR images with a wide dynamic range of brightness levels is related to the execution of operations outside the buffer in memory. Exploiting this vulnerability could allow an attacker to cause a system failure...

CVE-2026-59985

A flaw was found in OpenEXR. A remote attacker could provide a specially crafted RLE-compressed EXR image, which causes a 64-bit unpacked size to truncate before memory allocation. This leads to a heap out-of-bounds read when unpack32bit attempts to read beyond the allocated buffer. Successful...
