Michael S. Tsirkin discovered a flaw in how the Linux kernel's KVM
subsystem allocates memory slots for the guest's address space. A local
user could exploit this flaw to gain system privileges or obtain sensitive
information from kernel memory. (CVE-2013-1943)

A flaw was discovered in the SCTP (stream control transfer protocol)
network protocol's handling of duplicate cookies in the Linux kernel. A
remote attacker could exploit this flaw to cause a denial of service
(system crash) on another remote user querying the SCTP connection.
(CVE-2013-2206)

Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the
Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2013-4162)");
