I've since been contacted by the researcher and have been told that CVE-2016-5696 was reserved by mitre for this issue. I'd like to withdraw the usage of this CVE number and use CVE-2016-5696. Sorry for any confusion. Wade Mealing On Tue, Jul 12, 2016 at 2:33 PM, Wade Mealing <wmealing () redhat com> wrote:
Gday, Red Hat Product Security has been made aware of an important issue in the Linux kernel's implementation of challenge ACKS as specified in RFC 5961. An attacker which knows a connections client IP, server IP and server port can abuse the challenge ACK mechanism to determine the accuracy of a normally 'blind' attack on the client or server. Successful exploitation of this flaw could allow a remote attacker to inject or control a TCP stream contents in a connection between a Linux device and its connected client/server. * This does NOT mean that cryptographic information is exposed. * This is not a Man in the Middle (MITM) attack.
