An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds
read in ImfOptimizedPixelReading.h. (CVE-2020-11758)

An issue was discovered in OpenEXR before 2.4.1. Because of integer
overflows in CompositeDeepScanLine::Data::handleDeepFrameBuffer and
readSampleCountForLineBlock, an attacker can write to an out-of-bounds
pointer. (CVE-2020-11759)

read during RLE uncompression in rleUncompress in ImfRle.cpp.
(CVE-2020-11760)

An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds
read during Huffman uncompression, as demonstrated by FastHufDecoder::refill
in ImfFastHuf.cpp. (CVE-2020-11761)

An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds
read and write in DwaCompressor::uncompress in ImfDwaCompressor.cpp when
handling the UNKNOWN compression case. (CVE-2020-11762)

An issue was discovered in OpenEXR before 2.4.1. There is an std::vector
out-of-bounds read and write, as demonstrated by ImfTileOffsets.cpp.
(CVE-2020-11763)
