Receipt of a specific MPLS or IPv6 packet on the core facing interface of an MX Series device configured for Broadband Edge (BBE) service may trigger a kernel crash (vmcore), causing the device to reboot. The issue is specific to the processing of packets destined to BBE clients connected to MX Series subscriber management platforms. This issue affects MX Series running Juniper Networks Junos OS: 17.2 versions starting from17.2R2-S6, 17.2R3 and later releases, prior to 17.2R3-S3; 17.3 versions starting from 17.3R2-S4, 17.3R3-S2 and later releases, prior to 17.3R2-S5, 17.3R3-S5; 17.4 versions starting from 17.4R2 and later releases, prior to 17.4R2-S7,17.4R3; 18.1 versions starting from 18.1R2-S3, 18.1R3 and later releases, prior to 18.1R3-S6; 18.2 versions starting from18.2R1-S1, 18.2R2 and later releases, prior to 18.2R3-S2; 18.2X75 versions prior to 18.2X75-D51, 18.2X75-D60; 18.3 versions prior to 18.3R3; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R1-S3, 19.1R2; 19.2 versions prior to 19.2R1-S2, 19.2R2.

Jan 15, 2020Specific IPv6 packets sent by clients processed by the Routing Engine (RE) are improperly handled.CVE-2020-1603 · Network & remote access · Juniper Networks · reported by sirt@juniper.netHigh 8.6
Specific IPv6 packets sent by clients processed by the Routing Engine (RE) are improperly handled. These IPv6 packets are designed to be blocked by the RE from egressing the RE. Instead, the RE allows these specific IPv6 packets to egress the RE, at which point a mbuf memory leak occurs within the Juniper Networks Junos OS device. This memory leak eventually leads to a kernel crash (vmcore), or the device hanging and requiring a power cycle to restore service, creating a Denial of Service (DoS) condition. During the time where mbufs are rising, yet not fully filled, some traffic from client devices may begin to be black holed. To be black holed, this traffic must match the condition where this traffic must be processed by the RE. Continued receipt and attempted egress of these specific IPv6 packets from the Routing Engine (RE) will create an extended Denial of Service (DoS) condition. Scenarios which have been observed are: 1. In a single chassis, single RE scenario, the device will hang without vmcore, or a vmcore may occur and then hang. In this scenario the device needs to be power cycled. 2. In a single chassis, dual RE scenario, the device master RE will fail over to the backu

Aug 13, 2019An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11.CVE-2017-18509 · Computers, phones & browsers · Linux · reported by MITREHigh 7.8
An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.

Apr 10, 2019Specific IPv6 DHCP packets received by the jdhcpd daemon will cause a memory resource consumption issue to occur on a Junos OS device using the jdhcpd daemon coCVE-2019-0031 · Network & remote access · Juniper Networks · reported by sirt@juniper.netHigh 7.5
Specific IPv6 DHCP packets received by the jdhcpd daemon will cause a memory resource consumption issue to occur on a Junos OS device using the jdhcpd daemon configured to respond to IPv6 requests. Once started, memory consumption will eventually impact any IPv4 or IPv6 request serviced by the jdhcpd daemon, thus creating a Denial of Service (DoS) condition to clients requesting and not receiving IP addresses. Additionally, some clients which were previously holding IPv6 addresses will not have their IPv6 Identity Association (IA) address and network tables agreed upon by the jdhcpd daemon after the failover event occurs, which leads to more than one interface, and multiple IP addresses, being denied on the client. Affected releases are Juniper Networks Junos OS: 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2.
