The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has OpenEXR packages installed that are affected by multiple vulnerabilities:
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 std::vector out-of-bounds read and write, as demonstrated by ImfTileOffsets.cpp. (CVE-2020-11763)
An issue was discovered in OpenEXR before 2.4.1. There is an out-of-bounds write in copyIntoFrameBuffer in ImfMisc.cpp. (CVE-2020-11764)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
