A NULL pointer dereference flaw was found in the way openjpeg 2.1.2 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.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
