CVE-2014-1690 [LOW] Linux kernel (Saucy HWE) vulnerabilities
Title: Linux kernel (Saucy HWE) vulnerabilities
Summary: Several security issues were fixed in the kernel.
An information leak was discovered in the Linux kernel when built with the
NetFilter Connection Tracking (NF_CONNTRACK) support for IRC protocol
(NF_NAT_IRC). A remote attacker could exploit this flaw to obtain
potentially sensitive kernel information when communicating over a client-
to-client IRC connection(/dcc) via a NAT-ed network. (CVE-2014-1690)
Matthew Thode reported a denial of service vulnerability in the Linux
kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN
capability (and the SELinux mac_admin permission if running in enforcing
mode) could exploit this flaw to cause a denial of service (kernel crash).

CVE-2014-1874 Kernel: SELinux: local denial-of-service
Linux kernel built with the NSA SELinux Support(CONFIG_SECURITY_SELINUX) is
vulnerable to a crash caused by an empty SELinux security context value. If a
file has an empty security context, listing it via 'ls(1)' could trigger this
crash. Only user/processes with CAP_MAC_ADMIN privileges are allowed to set
the SELinux security context of a file.
A user/process with CAP_MAC_ADMIN privileges could use this flaw to crash the
kernel, resulting in a DoS.
