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

Description The issue is related to a heap buffer overflow in the getChunkOffsetTableSize() function in IlmImf/ImfMisc.cpp. This overflow can occur due to invalid chunkCount attributes. The exploitation of this issue may allow an attacker to cause a denial of service.
