Description

A flaw was found during a call to ConformPixelInfo() in the SetImageAlphaChannel() routine of /MagickCore/channel.c. This issue causes a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed() or GetPixelBlue()[1] is called. This flaw can occur when an attacker can submit a malicious image file to be processed by ImageMagick and could lead to a denial of service. The highest threat from this vulnerability is to system availability.
