The bmpreadinfoheader function in bin/jp2/convertbmp.c in OpenJPEG 2.2.0 does not reject headers with a zero biBitCount, which allows remote attackers to cause a denial of service (memory allocation failure) in the opjimagecreate function in lib/openjp2/image.c, related to the opjalignedallocn function in opj_malloc.c.
