The jp2_colr_destroy function in jp2_cod.c in JasPer before 1.900.13 allows remote attackers to cause a denial of service (NULL pointer dereference) by leveraging incorrect cleanup of JP2 box data on error. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-8887.
The product dereferences a pointer that it expects to be valid but is NULL.
