CVE-2019-0048


TITLE

Juniper Networks Junos OS Vulnerabilities related to security functions

Trust: 0.8

sources: JVNDB: JVNDB-2019-006594

DESCRIPTION

On EX4300 Series switches with TCAM optimization enabled, incoming multicast traffic matches an implicit loopback filter rule first, since it has high priority. This rule is meant for reserved multicast addresses 224.0.0.x, but incorrectly matches on 224.x.x.x. Due to this bug, when a firewall filter is applied on the loopback interface, other firewall filters might stop working for multicast traffic. The command 'show firewall filter' can be used to confirm whether the filter is working. This issue only affects the EX4300 switch. No other products or platforms are affected by this vulnerability. This issue affects: Juniper Networks Junos OS: 14.1X53 versions prior to 14.1X53-D51, 14.1X53-D115 on EX4300 Series; 17.1 versions prior to 17.1R3 on EX4300 Series; 17.2 versions prior to 17.2R3-S2 on EX4300 Series; 17.3 versions prior to 17.3R3-S3 on EX4300 Series; 17.4 versions prior to 17.4R2-S5, 17.4R3 on EX4300 Series; 18.1 versions prior to 18.1R3-S1 on EX4300 Series; 18.2 versions prior to 18.2R2 on EX4300 Series; 18.3 versions prior to 18.3R2 on EX4300 Series. Juniper Networks Junos OS Contains vulnerabilities related to security features.Information may be tampered with. The operating system provides a secure programming interface and Junos SDK. The following products and versions are affected: Juniper Networks Junos OS Release 14.1X53, Release 17.1, Release 17.2, Release 17.3, Release 17.4, Release 18.1, Release 18.2, Release 18.3
