Vulnerability from github – Published: 2025-12-30 22:54 – Updated: 2025-12-30 22:54

Summary

ImageMagick's failure to limit the depth of SVG file reads caused a DoS attack

Details

Summary

Using Magick to read a malicious SVG file resulted in a DoS attack.

Details

bt obtained using gdb:

#4 0x0000555555794c9c in ResizeMagickMemory (memory=0x7fffee203800, size=391344) at MagickCore/memory.c:1443
#5 0x0000555555794e5a in ResizeQuantumMemory (memory=0x7fffee203800, count=48918, quantum=8) 
at MagickCore/memory.c:1508
#6 0x0000555555acc8ed in SVGStartElement (context=0x517000000080, name=0x5190000055e3 "g", attributes=0x0) 
at coders/svg.c:1254
#7 0x00007ffff6799b1c in xmlParseStartTag () at /lib/x86_64-linux-gnu/libxml2.so.2
#8 0x00007ffff68c7bb8 in () at /lib/x86_64-linux-gnu/libxml2.so.2
#9 0x00007ffff67a03f1 in xmlParseChunk () at /lib/x86_64-linux-gnu/libxml2.so.2

This is related to the SVGStartElement and ResizeQuantumMemory functions.

PoC

Generate an SVG file
Read this file using Magick:

./magick /data/ylwang/Tools/LargeScan/targets/ImageMagick/test++/1.svg null

Causes a DoS Attack

My 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:

PS C:\Program Files\ImageMagick-7.1.2-Q8> .\magick.exe -ping 1.svg null:
PS C:\Program Files\ImageMagick-7.1.2-Q8> echo $LASTEXITCODE
-1073741571

The error code -1073741571 indicates a crash due to a stack overflow.

Impact

This is a DoS vulnerability and all applications using Magick to parse SVG files are affected.

Severity ?

5.3 (Medium)
