Description Laura Pardo 2019-01-09 20:09:01 UTC

A flaw was found in ImageMagick before 7.0.8-16. In coders/bmp.c, an input file can result in an infinite loop and hang, with high CPU and memory consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.
