15 Jan 2021 — A sensitive information disclosure vulnerability in delta-export configuration utility (dexp) of Juniper Networks Junos OS may allow a locally authenticated shell user the ability to create and read database files generated by the dexp utility, including password hashes of local users. Since dexp is shipped with setuid permissions enabled and is owned by the root user, this vulnerability may allow a local privileged user the ability to run dexp with root privileges and access sensitive information in the de... • https://kb.juniper.net/JSA11114 • CWE-250: Execution with Unnecessary Privileges CWE-269: Improper Privilege Management •

CVE-2021-0203 – Junos OS: EX and QFX5K Series: Storm Control does not work as expected when Redundant Trunk Group is configured
https://notcve.org/view.php?id=CVE-2021-0203
15 Jan 2021 — On Juniper Networks EX and QFX5K Series platforms configured with Redundant Trunk Group (RTG), Storm Control profile applied on the RTG interface might not take affect when it reaches the threshold condition. Storm Control enables the device to monitor traffic levels and to drop broadcast, multicast, and unknown unicast packets when a specified traffic level is exceeded, thus preventing packets from proliferating and degrading the LAN. Note: this issue does not affect EX2200, EX3300, EX4200, and EX9200 Seri... • https://kb.juniper.net/JSA11093 • CWE-794: Incomplete Filtering of Multiple Instances of Special Elements •

CVE-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 •
