Description Andrej Nemec 2017-08-31 09:28:52 EDT

The bmp_read_info_header 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 opj_image_create function in lib/openjp2/image.c,
related to the opj_aligned_alloc_n function in opj_malloc.c.
