Description:
 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.
Ubuntu-Description:
 Vasiliy Kulikov discovered that the netfilter code did not check certain
 strings copied from userspace. A local attacker with netfilter access could
 exploit this to read kernel memory or crash the system, leading to a denial
 of service.
