  - It was found that the Linux kernel did not properly     account file descriptors passed over the unix socket     against the process limit. A local user could use this     flaw to exhaust all available memory on the     system.(CVE-2013-4312)

  - 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)
