CVE-2017-11449

Published: 19 July 2017

coders/mpc.c in ImageMagick before 7.0.6-1 does not enable seekable streams and thus cannot validate blob sizes, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an image received from stdin.
