+	    running on 64-bit machines, allows context-dependent attackers to

+	  <p>Using a crafted tar file bsdtar can perform an out-of-bounds memory
+	    read which will lead to a SEGFAULT. The issue exists when the

+	    defined in byte offset [16-19] If ASLR is disabled, the issue can
+	    lead to an infinite loop.</p>
