Subject: jasper: memory allocation failure in jas_malloc (jas_malloc.c)

Description:
jasper is an open-source initiative to provide a free software-based reference 
implementation of the codec specified in the JPEG-2000 Part-1 standard.

Another round of fuzzing on an updated version (1.900.5) revealed a memory 
allocation failure.

The complete ASan output:

# imginfo -f $FILE
