Name of the Vulnerable Software and Affected Versions ImageMagick versions 7.0.7-29 and earlier

Description The issue is related to a null pointer dereference in the ReadOneJNGImage function of the coders/png.c component. This can be exploited by a remote attacker to cause a denial of service, resulting in a WriteBlob assertion failure and application exit, via a crafted file.

Recommendations For ImageMagick versions 7.0.7-29 and earlier, as a temporary workaround, consider disabling the ReadOneJNGImage function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
