Description Martin Prpič 2017-03-31 13:23:36 UTC

It was found that the fixes for CVE-2016-8866 and CVE-2016-8862 were incomplete:

The ReadPCXImage function in coders/pcx.c in ImageMagick 7.0.4.9 allows remote attackers to cause a denial of service (attempted large memory allocation and application crash) via a crafted file.
