1) Input validation error (CVE-ID: CVE-2014-3873)

The ktrace utility in the FreeBSD kernel 8.4 before p11, 9.1 before p14, 9.2 before p7, and 9.3-BETA1 before p1 uses an incorrect page fault kernel trace entry size, which allows local users to obtain sensitive information from kernel memory via a kernel process trace.
