  "description": "CImg Library is a C\u002B\u002B library for image processing. Prior to version 4.0.0 in \u0060_load_analyze()\u0060, the header_size field is read as an \u0060unsigned int\u0060 from the first 4 bytes of an Analyze/NIfTI file and passed directly to \u0060new unsigned char[header_size]\u0060 without being bounded against the actual file size. A value up to ~4 GB is accepted. If the subsequent \u0060fread\u0060 returns \u0060short\u0060  as it will for any malformed file), the function throws a \u0060CImgIOException\u0060 and the allocated buffer is never freed. A 6-byte crafted file is sufficient to trigger an allocation of ~1.3 GB per call, with the full allocation leaked on every error path. The issue is reachable via \u0060load_analyze()\u0060 and the generic \u0060load()\u0060 when the file extension is .hdr, .img, or .nii. Version 4.0.0 fixes the issue.",
