Header::readfrom in IlmImf/ImfHeader.cpp in OpenEXR 2.2.0 allows remote attackers to cause a denial of service (excessive memory allocation) via a crafted file that is accessed with the ImfOpenInputFile function in IlmImf/ImfCRgbaFile.cpp. NOTE: The maintainer and multiple third parties believe that this vulnerability isn't valid
In OpenEXR 2.2.0, a crafted image causes a heap-based buffer over-read in the hufDecode function in IlmImf/ImfHuf.cpp during exrmaketiled execution; it may result in denial of service or possibly unspecified other impact.
In OpenEXR 2.2.0, an invalid write of size 8 in the storeSSE function in ImfOptimizedPixelReading.h could cause the application to crash or execute arbitrary code.
In OpenEXR 2.2.0, an invalid write of size 1 in the bufferedReadPixels function in ImfInputFile.cpp could cause the application to crash or execute arbitrary code.
Multiple integer overflows in OpenEXR 1.2.2 and 1.6.1 allow context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors that trigger heap-based buffer overflows, related to (1) the Imf::PreviewImage::PreviewImage function and (2) compressor constructors. NOTE: some of these details are obtained from third party information.
