  - The udp_v6_push_pending_frames function in     net/ipv6/udp.c in the IPv6 implementation in the Linux     kernel through 3.10.3 makes an incorrect function call     for pending data, which allows local users to cause a     denial of service (BUG and system crash) via a crafted     application that uses the UDP_CORK option in a     setsockopt system call.(CVE-2013-4162)

  - The ip6_append_data_mtu function in     net/ipv6/ip6_output.c in the IPv6 implementation in the     Linux kernel through 3.10.3 does not properly maintain     information about whether the IPV6_MTU setsockopt     option had been specified, which allows local users to     cause a denial of service (BUG and system crash) via a     crafted application that uses the UDP_CORK option in a     setsockopt system call.(CVE-2013-4163)

  - Use-after-free vulnerability in drivers/net/tun.c in     the Linux kernel through 3.11.1 allows local users to     gain privileges by leveraging the CAP_NET_ADMIN     capability and providing an invalid tuntap interface     name in a TUNSETIFF ioctl call.(CVE-2013-4343)

  - Off-by-one error in the get_prng_bytes function in     crypto/ansi_cprng.c in the Linux kernel through 3.11.4     makes it easier for context-dependent attackers to     defeat cryptographic protection mechanisms via multiple     requests for small amounts of data, leading to improper     management of the state of the consumed     data.(CVE-2013-4345)
