Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to integer overflow in ImageChannel::resize in OpenEXRUtil when parsing a crafted EXR image or using the public API with a crafted dataWindow. A remote attacker can supply crafted image dimensions that cause an undersized heap allocation and subsequent out-of-bounds write to execute arbitrary code.

User interaction is required to open or process a crafted EXR image.
