This is duplicate of CVE-2011-4517 (bug 747726). The problem was in the jpc_crg_getparms() function, which incorrectly allocated memory for cstate->numcomps. When allocating memory, function assume that each item in the array has sizeof(uint_fast16_t). However, it later handled each item as being of type jpc_crgcomp_t, a structure containing two uint_fast16_t type variables. Therefore, it allocated approximately half of the required memory, leading to heap-based buffer overflow later. In Red Hat products, this issue was already corrected in previous updates for CVE-2011-4517. Problem was addressed upstream in version 1.900.5 via this commit: https://github.com/mdadams/jasper/commit/0d22460816ea58e74a124158fa6cc48efb709a47
