15 Jan 2020 — On EX4300, EX4600, QFX3500, and QFX5100 Series, a vulnerability in the IP firewall filter component may cause the firewall filter evaluation of certain packets to fail. This issue only affects firewall filter evaluation of certain packets destined to the device Routing Engine (RE). This issue does not affect the Layer 2 firewall filter evaluation nor does it affect the Layer 3 firewall filter evaluation destined to connected hosts. This issue may occur when evaluating both IPv4 or IPv6 packets. This issue a... • https://kb.juniper.net/JSA10983 • CWE-284: Improper Access Control •

11 Jul 2019 — 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 af... • https://kb.juniper.net/JSA10942 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

10 Apr 2019 — In MPLS environments, receipt of a specific SNMP packet may cause the routing protocol daemon (RPD) process to crash and restart. By continuously sending a specially crafted SNMP packet, an attacker can repetitively crash the RPD process causing prolonged denial of service. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS : 12.1X46 versions prior to 12.1X46-D77 on SRX Series; 12.3 versions prior to 12.3R12-S10; 12.3X48 versions prior... • https://kb.juniper.net/JSA10935 • CWE-404: Improper Resource Shutdown or Release •

10 Apr 2019 — On EX4300-MP Series devices with any lo0 filters applied, transit network traffic may reach the control plane via loopback interface (lo0). The device may fail to forward such traffic. This issue affects Juniper Networks Junos OS 18.2 versions prior to 18.2R1-S2, 18.2R2 on EX4300-MP Series. This issue does not affect any other EX series devices. En los dispositivos de la serie EX4300-MP con cualquier filtro lo0 aplicado, el tráfico de la red de tránsito puede alcanzar el plano de control por medio de la int... • https://kb.juniper.net/JSA10933 • CWE-284: Improper Access Control •

10 Apr 2019 — A certain sequence of valid BGP or IPv6 BFD packets may trigger a stack based buffer overflow in the Junos OS Packet Forwarding Engine manager (FXPC) process on QFX5000 series, EX4300, EX4600 devices. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code execution. Affected releases are Juniper Networks Junos OS on QFX 5000 series, EX4300, EX4600 are: 14.1X53; 15.1X53 versions prior to 15.1X53-D235; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versi... • http://www.securityfocus.com/bid/107897 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

10 Oct 2018 — Receipt of a specific MPLS packet may cause the routing protocol daemon (RPD) process to crash and restart or may lead to remote code execution. By continuously sending specific MPLS packets, an attacker can repeatedly crash the RPD process causing a sustained Denial of Service. This issue affects both IPv4 and IPv6. This issue can only be exploited from within the MPLS domain. End-users connected to the CE device cannot cause this crash. • http://www.securitytracker.com/id/1041847 • CWE-20: Improper Input Validation •
