Vulnerability Summary

net/ipv4/netfilter/ip_tables.c in the IPv4 implementation in the Linux kernel prior to 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.
