tag_summary   = "Several vulnerabilities have been discovered in the FreeBSD kernel that may
lead to a denial of service or privilege escalation. The Common
Vulnerabilities and Exposures project identifies the following problems:

CVE-2013-5691 
Loganaden Velvindron and Gleb Smirnoff discovered that the SIOCSIFADDR,
SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK ioctl requests do not
perform input validation or verify the caller's credentials.
Unprivileged user with the ability to run arbitrary code can cause any
network interface in the system to perform the link layer actions
associated with the above ioctl requests or trigger a kernel panic by
passing a specially crafted address structure which causes a network
interface driver to dereference an invalid pointer.

CVE-2013-5710 
Konstantin Belousov discovered that the nullfs(5) implementation of the
VOP_LINK(9) VFS operation does not check whether the source and target of
the link are both in the same nullfs instance. It is therefore possible to
create a hardlink from a location in one nullfs instance to a file in
another, as long as the underlying (source) filesystem is the same. If
multiple nullfs views into the same filesystem are mounted in different
locations, a user may gain write access to files which are nominally on
a read-only filesystem.";
tag_vuldetect = "This check tests the installed software version using the apt package manager.";
