CVE-2013-4345 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-4345):
  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.
