Description Laura Pardo 2018-04-05 00:00:43 UTC 
A flaw was found in ImageMagick 7.0.7-26 Q16. An 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.
