(CVE-2020-15304).

An issue was discovered in OpenEXR before v2.5.2. Invalid chunkCount attributes
could cause a heap buffer overflow in getChunkOffsetTableSize() in
IlmImf/ImfMisc.cpp (CVE-2020-15306).

A heap-based buffer overflow vulnerability exists in Academy Software
Foundation OpenEXR 2.3.0 in chunkOffsetReconstruction in
ImfMultiPartInputFile.cpp that can cause a denial of service via a crafted EXR
file (CVE-2020-16587).

2.3.0 in generatePreview in makePreview.cpp that can cause a denial of
service via a crafted EXR file (CVE-2020-16588).

A head-based buffer overflow exists in Academy Software Foundation OpenEXR
