Key facts

Description

An Out-of-bounds Write vulnerability in the Internet Key Exchange Protocol daemon (iked) of Juniper Networks Junos OS on SRX series and MX with SPC3 allows an authenticated, network-based attacker to cause a Denial of Service (DoS). iked will crash and restart, and the tunnel will not come up when a peer sends a specifically formatted payload during the negotiation. This will impact other IKE negotiations happening at the same time. Continued receipt of this specifically formatted payload will lead to continuous crashing of iked and thereby the inability for any IKE negotiations to take place. Note that this payload is only processed after the authentication has successfully completed. So the issue can only be exploited by an attacker who can successfully authenticate. This issue affects Juniper Networks Junos OS on SRX Series, and MX Series with SPC3: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R3-S9; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R3-S1; 21.4 versions prior to 21.4R2-S1, 21.4R3; 22.1 versions prior to 22.1R1-S2, 22.1R2.
