kernel: ipv4: netfilter: ip_tables: fix infoleak to userspace

net/ipv4/netfilter/iptables.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...

kernel: ipv6: netfilter: ip6_tables: fix infoleak to userspace

net/ipv6/netfilter/ip6tables.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...

kernel: netfilter: ebtables: enforce CAP_NET_ADMIN

net/bridge/netfilter/ebtables.c in the ebtables module in the netfilter framework in the Linux kernel before 2.6.33-rc4 does not require the CAPNETADMIN capability for setting or modifying rules, which allows local users to bypass intended access restrictions and configure arbitrary network-traff...

security flaw

Race condition in the doaddcounters function in netfilter for Linux kernel 2.6.16 allows local users with CAPNETADMIN capabilities to read kernel memory by triggering the race condition in a way that produces a size value that is inconsistent with allocated memory, which leads to a buffer over-re...
