CVSS: 7.5EPSS: 0%CPEs: 122EXPL: 0CVE-2020-1679 – Junos OS: PTX/QFX Series: Kernel Routing Table (KRT) queue stuck after packet sampling a malformed packet when the tunnel-observation mpls-over-udp configuration is enabled.
https://notcve.org/view.php?id=CVE-2020-1679
16 Oct 2020 — On Juniper Networks PTX and QFX Series devices with packet sampling configured using tunnel-observation mpls-over-udp, sampling of a malformed packet can cause the Kernel Routing Table (KRT) queue to become stuck. KRT is the module within the Routing Process Daemon (RPD) that synchronized the routing tables with the forwarding tables in the kernel. This table is then synchronized to the Packet Forwarding Engine (PFE) via the KRT queue. Thus, when KRT queue become stuck, it can lead to unexpected packet forw... • https://kb.juniper.net/JSA11076 • CWE-20: Improper Input Validation •
CVSS: 5.3EPSS: 0%CPEs: 237EXPL: 0CVE-2020-1661 – Junos OS: jdhcpd process crash when forwarding a malformed DHCP packet.
https://notcve.org/view.php?id=CVE-2020-1661
16 Oct 2020 — On Juniper Networks Junos OS devices configured as a DHCP forwarder, the Juniper Networks Dynamic Host Configuration Protocol Daemon (jdhcp) process might crash when receiving a malformed DHCP packet. This issue only affects devices configured as DHCP forwarder with forward-only option, that forward specified DHCP client packets, without creating a new subscriber session. The jdhcpd daemon automatically restarts without intervention, but continuous receipt of the malformed DHCP packet will repeatedly crash ... • https://kb.juniper.net/JSA11056 •
