  "summary" : "ImageMagick's failure to limit the depth of SVG file reads caused a DoS attack",
  "details" : "### Summary\n\nUsing Magick to read a malicious SVG file resulted in a DoS attack.\n\n### Details\n\nbt obtained using gdb:\n\n```\n#4 0x0000555555794c9c in ResizeMagickMemory (memory=0x7fffee203800, size=391344) at MagickCore/memory.c:1443\n#5 0x0000555555794e5a in ResizeQuantumMemory (memory=0x7fffee203800, count=48918, quantum=8) \nat MagickCore/memory.c:1508\n#6 0x0000555555acc8ed in SVGStartElement (context=0x517000000080, name=0x5190000055e3 \"g\", attributes=0x0) \nat coders/svg.c:1254\n#7 0x00007ffff6799b1c in xmlParseStartTag () at /lib/x86_64-linux-gnu/libxml2.so.2\n#8 0x00007ffff68c7bb8 in () at /lib/x86_64-linux-gnu/libxml2.so.2\n#9 0x00007ffff67a03f1 in xmlParseChunk () at /lib/x86_64-linux-gnu/libxml2.so.2\n```\n\nThis is related to the SVGStartElement and ResizeQuantumMemory functions.\n\n### PoC\n\n1. Generate an SVG file\n\n2. Read this file using Magick:\n\n```\n./magick /data/ylwang/Tools/LargeScan/targets/ImageMagick/test++/1.svg null\n```\n\n3. Causes a DoS Attack\n\nMy server has a large amount of memory, causing a stack overflow to take a long time. I'll use the Windows release version as an example:\n\n``` \nPS C:\\Program Files\\ImageMagick-7.1.2-Q8> .\\magick.exe -ping 1.svg null:\nPS C:\\Program Files\\ImageMagick-7.1.2-Q8> echo $LASTEXITCODE\n-1073741571\n```\n\nThe error code -1073741571 indicates a crash due to a stack overflow.\n\n### Impact\n\nThis is a DoS vulnerability and all applications using Magick to parse SVG files are affected.",
