Description Martin Prpič 2016-12-08 09:04:28 UTC 
A NULL pointer dereference flaw was found in the way openjpeg decoded certain input images. Due to a logic error in the code responsible for decoding the input image, an application using openjpeg to process image data could crash when processing a crafted image.
