CVE-2011-1172 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1172):
  net/ipv6/netfilter/ip6_tables.c in the IPv6 implementation in the Linux
  kernel before 2.6.39 does not place the expected '\0' character at the end
  of string data in the values of certain structure members, which allows
  local users to obtain potentially sensitive information from kernel memory
  by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and
  then reading the argument to the resulting modprobe process.

CVE-2011-1171 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1171):
  net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux
  kernel before 2.6.39 does not place the expected '\0' character at the end
  of string data in the values of certain structure members, which allows
  local users to obtain potentially sensitive information from kernel memory
  by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and
  then reading the argument to the resulting modprobe process.

CVE-2011-1170 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-1170):
  net/ipv4/netfilter/arp_tables.c in the IPv4 implementation in the Linux
  kernel before 2.6.39 does not place the expected '\0' character at the end
  of string data in the values of certain structure members, which allows
  local users to obtain potentially sensitive information from kernel memory
  by leveraging the CAP_NET_ADMIN capability to issue a crafted request, and
  then reading the argument to the resulting modprobe process.
