1) Information disclosure (CVE-ID: CVE-2013-6832)

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The nand_ioctl function in sys/dev/nand/nand_geom.c in the nand driver in the kernel in FreeBSD 10 and earlier does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted ioctl call.
