CVE-2021-0289 – Junos OS: User-defined ARP Policer isn't applied on Aggregated Ethernet (AE) interface until firewall process is restarted
https://notcve.org/view.php?id=CVE-2021-0289
When user-defined ARP Policer is configured and applied on one or more Aggregated Ethernet (AE) interface units, a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability between the Device Control Daemon (DCD) and firewall process (dfwd) daemons of Juniper Networks Junos OS allows an attacker to bypass the user-defined ARP Policer. In this particular case the User ARP policer is replaced with default ARP policer. To review the desired ARP Policers and actual state one can run the command "show interfaces <> extensive" and review the output. See further details below. An example output is: show interfaces extensive | match policer Policer: Input: __default_arp_policer__ <<< incorrect if user ARP Policer was applied on an AE interface and the default ARP Policer is displayed Policer: Input: jtac-arp-ae5.317-inet-arp <<< correct if user ARP Policer was applied on an AE interface For all platforms, except SRX Series: This issue affects Juniper Networks Junos OS: All versions 5.6R1 and all later versions prior to 18.4 versions prior to 18.4R2-S9, 18.4R3-S9 with the exception of 15.1 versions 15.1R7-S10 and later versions; 19.4 versions prior to 19.4R3-S3; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S2; 20.3 version 20.3R1 and later versions; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2; This issue does not affect Juniper Networks Junos OS versions prior to 5.6R1. • https://kb.juniper.net/JSA11191 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

https://notcve.org/view.php?id=CVE-2014-3812
The Juniper Junos Pulse Secure Access Service (SSL VPN) devices with IVE OS before 7.4r5 and 8.x before 8.0r1 and Junos Pulse Access Control Service (UAC) before 4.4r5 and 5.x before 5.0r1 enable cipher suites with weak encryption algorithms, which make it easier for remote attackers to obtain sensitive information by sniffing the network. Los dispositivos Juniper Junos Pulse Secure Access Service (SSL VPN) con IVE OS anterior a 7.4r5 y 8.x anterior a 8.0r1 y Junos Pulse Access Control Service (UAC) anterior a 4.4r5 y 5.x anterior a 5.0r1 habilitan suites de cifrado con algoritmos de codificación débiles, lo que facilita a atacantes remotos obtener información sensible mediante la captura de trafico de red. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10628 • CWE-310: Cryptographic Issues •
