Plane offline IPC of chassisd may time out on MX devices with MPC11E linecards
Product-Group=junos |
On MX2010/MX2020 with MPC11E linecards, plane offline IPC event might be stuck and the line cards may restart. This issue may happen if there is a run time CRC error on Cascaded PFE and when both the planes associated with the link fault are made offline. |

CSPF job might get stalled for new/existing LSP in high scale LSP setup
Product-Group=junos |
In an MPLS-TE scenario with high scale LSPs (for example, 20,000), CSPF job might get stalled for new/existing LSP if some configuration changes (which impacts the rpd process) are done when constrained shortest path first (CSPF) job is suspended and pending. Traffic Engineering Database CSPF job goes in a state where it is not able to recover till the time rpd process is restarted. This defect could only be observed in 20.2R1 or 20.2R1-EVO release. |

JSA11099 Junos OS Evolved: Receipt of certain valid BGP update packets from BGP peers may cause RPD to core when using REGEX. (CVE-2021-0209)
Product-Group=junos |
In Juniper Networks Junos OS Evolved an attacker sending certain valid BGP update packets may cause Junos OS Evolved to access an uninitialized pointer causing RPD to core leading to a Denial of Service (DoS). Please refer to https://kb.juniper.net/JSA11099 for more information. |

Category: SW PRs for SCBE3 fabric |
1553641 |
The fabric errors are observed and the FPC processes might get offlined with SCBE3, MPC3E-NG, or MPC3E and MPC7 or MPC10 in the increased-bandwidth fabric mode.
Product-Group=junos |
On MX240/MX480/MX960 platforms, with default "increased-bandwidth" fabric mode and SCBE3, if we have MPC3 or MPC3-NG exist on the system along with high bandwidth MPC, during high traffic situation or bursty traffic through the fabric towards MPC3/MPC3-NG. MX fabric might report unreachable destination condition and causes fabric healing to trigger in. This issue is exacerbated when having MPC7 or MPC10 line cards installed due to high fabric bandwidth that can be generated. |

Stream buffer memory leak might happen when UTM is configured under unified policies.
Product-Group=junos |
On all Junos platforms that support unified policies (layer 7 application), stream buffer memory leak might happen when Unified Threat Management (UTM) Antivirus Protection (AV)/ Antispam Filtering (AS)/Content Filtering (CF) is configured under unified policies. If the stream buffer memory is exhausted, traffic related to UTM will be affected. |

Synopsis |
Category: Virtual Router Redundancy Protocol |
1558560 |
Junos device might send VRRP advertisement packets in VRRP init or idle state before startup-silent-period timer expiry after performing GRES on VRRP master device with NSR disabled
Product-Group=junos |
If VRRP master device has dual Routing Engines (REs) and GRES enabled but nonstop-routing (NSR) disabled, after performing GRES, both REs will move to VRRP init then idle state and the new master RE will send VRRP advertisement packets in this stage before startup-silent-period timer expiry. Since the VRRP backup device can still receive the VRRP advertisement packets with higher priority, it will not transition to VRRP master state and hence cause the longer traffic downtime until the VRRP master device re-take the VRRP mastership after startup-silent-period timer expiry.
