ImageMagick 7.0.7-26 Q16 has excessive iteration in the DecodeLabImage and EncodeLabImage functions (coders/tiff.c), which results in a hang (tens of minutes) with a tiny PoC file. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted tiff file.
Weakness
The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed.
