Name of the Vulnerable Software and Affected Versions OpenEXR versions prior to 2.5.2

Description An issue in OpenEXR is related to the use of memory after it has been freed, specifically in the DeepScanLineInputFile::DeepScanLineInputFile() function. This can be caused by invalid input and may lead to a denial of service. The estimated number of potentially affected devices and details about real-world incidents are not provided.

Recommendations For versions prior to 2.5.2, update to version 2.5.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the DeepScanLineInputFile::DeepScanLineInputFile() function until a patch is available.
