CVE-2013-5666: Freebsd

Medium severity, CVSS 4.7. EPSS: 0.3% chance of exploitation in the next 30 days.

The sendfile system-call implementation in sys/kern/uipc_syscalls.c in the kernel in FreeBSD 9.2-RC1 and 9.2-RC2 does not properly pad transmissions, which allows local users to obtain sensitive information (kernel memory) via a length greater than the length of the file.
