A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by I

A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of a too large shift for 64-bit type ssize_t. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior.

This flaw affects ImageMagick versions prior to 7.0.9-0.
