This really is a duplicate of CVE-2011-4516 (bug 747726), with slightly different symptoms. The problem is missing check of the maximum value for the number of resolution levels (numrlvls) in the jpc_cox_getcompparms() function. This could lead to out-of-bounds write directly in the jpc_cox_getcompparms() function as originally described for CVE-2011-4516 - when writing to rlvls[] array inside jpc_coxcp_t type structure compparms. In case of the CVE-2016-8880 reproducer, out-of-bounds write in jpc_cox_getcompparms() was avoided, and a different out-of-bounds reads and writes were triggered in jpc_dec_cp_setfromcox() - reading from the mentioned rlvls[] array and writing to prcwidthexpns[] and prcheightexpns[] arrays inside of the ccp structure of type jpc_dec_ccp_t. In Red Hat products, this issue was already corrected in previous updates for CVE-2011-4516. Problem was addressed upstream in version 1.900.5 via this commit: https://github.com/mdadams/jasper/commit/0d22460816ea58e74a124158fa6cc48efb709a47
