for network sysctls are handled in the Linux kernel. An unprivileged local
user could exploit this flaw to have privileged access to files in
/proc/sys/net/. (CVE-2013-4270)

A flaw was discovered in the Linux kernel's dm snapshot facility. A remote
authenticated user could exploit this flaw to obtain sensitive information
or modify/corrupt data. (CVE-2013-4299)

Wannes Rombouts reported a vulnerability in the networking tuntap interface
of the Linux kernel. A local user with the CAP_NET_ADMIN capability could
leverage this flaw to gain full admin privileges. (CVE-2013-4343)

Alan Chester reported a flaw in the IPv6 Stream Control Transmission
Protocol (SCTP) of the Linux kernel. A remote attacker could exploit this
flaw to obtain sensitive information by sniffing network traffic.
(CVE-2013-4350)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP
Fragmentation Offload (UFO) processing. A remote attacker could leverage
this flaw to cause a denial of service (system crash). (CVE-2013-4387)

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP
Fragmenttation Offload (UFO). An unprivileged local user could exploit this
flaw to cause a denial of service (system crash) or possibly gain
administrative privileges. (CVE-2013-4470)";
