Name of the Vulnerable Software and Affected Versions ImageMagick versions prior to 7.0.11 ImageMagick versions prior to 6.9.12

Description A flaw was found in ImageMagick where a division by zero in WaveImage() of MagickCore/visual-effects.c may trigger undefined behavior via a crafted image file submitted to an application using ImageMagick. The highest threat from this issue is to system availability. Exploitation of this flaw may allow a remote attacker to cause a denial of service using a specially crafted image file.

Recommendations For versions prior to 7.0.11, update to version 7.0.11 or later. For versions prior to 6.9.12, update to version 6.9.12 or later. As a temporary workaround, consider disabling the WaveImage() function in MagickCore/visual-effects.c until a patch is available.
