kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...
