Description Andrej Nemec 2017-10-10 09:17:12 UTC

The AcquireResampleFilterThreadSet function in magick/resample-private.h in ImageMagick 7.0.7-4 mishandles failed memory allocation, which allows remote attackers to cause a denial of service (NULL Pointer Dereference in DistortImage in MagickCore/distort.c, and application crash) via unspecified vectors.
