 'cwe': ['CWE-189'], 'message': 'At many places in the code, jas_malloc or jas_recalloc was being
invoked with the size argument being computed in a manner that would not
allow integer overflow to be detected.  Now, these places in the code
have been modified to use special-purpose memory allocation functions
(e.g., jas_alloc2, jas_alloc3, jas_realloc2) that check for overflow.
This should fix many security problems.'
