Name of the Vulnerable Software and Affected Versions OpenEXR versions prior to 3.0.1

Description The issue is related to an integer overflow leading to a heap-buffer overflow in the DwaCompressor component of OpenEXR. This flaw can be exploited by an attacker to cause a denial of service, potentially crashing an application compiled with OpenEXR.

Recommendations For versions prior to 3.0.1, update to version 3.0.1 or later to resolve the issue. As a temporary workaround, consider disabling the DwaCompressor component until a patch is available. Restrict access to applications compiled with OpenEXR to minimize the risk of exploitation.
