Name of the Vulnerable Software and Affected Versions: OpenEXR versions prior to 3.0.0-beta

Description: The issue is related to an integer overflow in the B44 compression function of the OpenEXR library. This can be exploited by a remote attacker to cause a denial of service by opening specially crafted EXR files. The vulnerability affects the B44 uncompression functionality and can be triggered by submitting a crafted file to OpenEXR, potentially affecting application availability.

Recommendations: For versions prior to 3.0.0-beta, update to version 3.0.0-beta or later to resolve the issue. As a temporary workaround, consider restricting the use of the B44 compression function until a patch is available. Avoid opening specially crafted EXR files with the vulnerable version of OpenEXR to minimize the risk of exploitation.
