Juniper JUNOS 17.2

On EX2300, EX3400, EX4600, QFX3K and QFX5K series, firewall filter configuration cannot perform packet matching on any IPv6 extension headers. This issue may allow IPv6 packets that should have been blocked to be forwarded. IPv4 packet filtering is unaffected by this vulnerability. Affected releases are Juniper Networks Junos OS on EX and QFX series;: 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R7; 15.1X53 versions prior to 15.1X53-D234 on QFX5200/QFX5110 series; 15.1X53 versions prior to 15.1X53-D591 on EX2300/EX3400 series; 16.1 versions prior to 16.1R7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2.

Receipt of a specially crafted IPv6 exception packet may be able to trigger a kernel crash (vmcore), causing the device to reboot. The issue is specific to the processing of Broadband Edge (BBE) client route processing on MX Series subscriber management platforms, introduced by the Tomcat (Next Generation Subscriber Management) functionality in Junos OS 15.1. This issue affects no other platforms or configurations. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S2, 15.1R8 on MX Series; 16.1 versions prior to 16.1R4-S11, 16.1R7-S2, 16.1R8 on MX Series; 16.2 versions prior to 16.2R3 on MX Series; 17.1 versions prior to 17.1R2-S9, 17.1R3 on MX Series; 17.2 versions prior to 17.2R2-S6, 17.2R3 on MX Series; 17.3 versions prior to 17.3R2-S4, 17.3R3-S2, 17.3R4 on MX Series; 17.4 versions prior to 17.4R2 on MX Series; 18.1 versions prior to 18.1R2-S3, 18.1R3 on MX Series; 18.2 versions prior to 18.2R1-S1, 18.2R2 on MX Series.

On MX Series and M120/M320 platforms configured in a Broadband Edge (BBE) environment, subscribers logging in with DHCP Option 50 to request a specific IP address will be assigned the requested IP address, even if there is a static MAC to IP address binding in the access profile. In the problem scenario, with a hardware-address and IP address configured under address-assignment pool, if a subscriber logging in with DHCP Option 50, the subscriber will not be assigned an available address from the matched pool, but will still get the requested IP address. A malicious DHCP subscriber may be able to utilize this vulnerability to create duplicate IP address assignments, leading to a denial of service for valid subscribers or unauthorized information disclosure via IP address assignment spoofing. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S2, 15.1R8; 16.1 versions prior to 16.1R4-S12, 16.1R7-S2, 16.1R8; 16.2 versions prior to 16.2R2-S7, 16.2R3; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3; 17.3 versions prior to 17.3R2-S4, 17.3R3; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2-S3, 18.1R3.
