Comment 3 Tomas Hoger 2016-12-15 13:03:05 UTC

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:
