Vulnerabilidades de Juniper Networks

A Improper Validation of Specified Quantity in Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a denial of service via a malformed RSVP packet when RSVP is enabled on the receiving interface.

A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos on MX Series routers allows an unauthenticated network attacker to cause a denial of service via an eBGP route update when HFRR link protection is configured in a VRF.

A NULL Pointer Dereference vulnerability in the rpd process of Juniper Networks Junos OS on MX Series and Junos OS Evolved on ACX Series allows an unauthenticated adjacent attacker to cause a denial of service via an IGMPv3 membership report received on a directly connected network.

A Reachable Assertion vulnerability in the bfdd daemon of Juniper Networks Junos OS and Junos OS Evolved platforms allows an unauthenticated adjacent attacker to cause a denial of service by restarting the daemon via crafted BFD session traffic.

An Improper Handling of Length Parameter Inconsistency vulnerability in L2ALM of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to obtain stale PFE packet memory via VXLAN overlay-ping traffic sent to a local VTEP.

An Improper Release of Memory Before Removing Last Reference vulnerability in the l2ald process of Juniper Networks Junos OS and Junos OS Evolved on QFX5K-family platforms allows a configured EVPN peer to cause a denial of service through memory exhaustion via EVPN-VXLAN active-active multihoming route processing.

An Improper Release of Memory Before Removing Last Reference vulnerability in the l2cpd process of Juniper Networks Junos OS and Junos OS Evolved platforms allows an adjacent unauthenticated attacker to cause l2cpd memory exhaustion and Layer 2 control-plane disruption via LLDP traffic when fast receive processing is enabled.

An Allocation of Resources Without Limits or Throttling vulnerability in the l2cpd process of Juniper Networks Junos OS allows an adjacent unauthenticated attacker to cause a denial of service and l2cpd restart via FNP-enabled Layer 2 interfaces. The issue is triggered when the FNP feature is enabled on a VPLS routing instance with VLAN-VPLS encapsulation enabled. This issue affects all platforms except the PTX Series and SRX Series.

An Improper Validation of Consistency within Input vulnerability in the l2cpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated Layer 2 attacker to cause a denial of service in associated Layer 2 control protocols via a crafted MVRP Ethernet frame sent to an MVRP-enabled interface.

A Reachable Assertion vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to crash the routing process via RSVP-TE associated-bidirectional LSP signaling.

An Out-of-bounds Write Out-of-bounds Write vulnerability in lacpd of Juniper Networks Junos OS Evolved allows a Layer-2-adjacent attacker to cause a denial of service via a crafted frame received on an LACP-enabled aggregated-Ethernet member port.

A Numeric Truncation Error vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to crash the routing process via MPLS-TE fast-reroute signaling.
