An issue was discovered in the routes middleware in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. By making API requests involving nonexistent controllers, an authenticated user may cause the API worker to consume increasing amounts of memory, resulting in API performance degradation or denial of service.
CWE-772
CVE-2021-40008
There is a memory leak vulnerability in CloudEngine 12800 V200R019C00SPC800, CloudEngine 5800 V200R019C00SPC800, CloudEngine 6800 V200R019C00SPC800 and CloudEngine 7800 V200R019C00SPC800. The software does not sufficiently track and release allocated memory while parse a series of crafted binary messages, which could consume remaining memory. Successful exploit could cause memory exhaust.
CVE-2021-34581
Missing Release of Resource after Effective Lifetime vulnerability in OpenSSL implementation of WAGO 750-831/xxx-xxx, 750-880/xxx-xxx, 750-881, 750-889 in versions FW4 up to FW15 allows an unauthenticated attacker to cause DoS on the device.

CVE-2021-31378
In broadband environments, including but not limited to Enhanced Subscriber Management, (CHAP, PPP, DHCP, etc.), on Juniper Networks Junos OS devices where RADIUS servers are configured for managing subscriber access and a subscriber is logged in and then requests to logout, the subscriber may be forced into a “Terminating” state by an attacker who is able to send spoofed messages appearing to originate from trusted RADIUS server(s) destined to the device in response to the subscriber’s request. These spoofed messages cause the Junos OS General Authentication Service (authd) daemon to force the broadband subscriber into this “Terminating” state which the subscriber will not recover from thereby causing a Denial of Service (DoS) to the endpoint device. Once in the “Terminating” state, the endpoint subscriber will no longer be able to access the network. Restarting the authd daemon on the Junos OS device will temporarily clear the subscribers out of the “Terminating” state. As long as the attacker continues to send these spoofed packets and subscribers request to be logged out, the subscribers will be returned to the “Terminating” state thereby creating a persistent Denial of Service to the subscriber. An indicator of compromise may be seen by displaying the output of “show subscribers summary”. The presence of subscribers in the “Terminating” state may indicate the issue is occurring. This issue affects: Juniper Networks Junos OS 17.3 versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R2-S8, 18.4R3-S9; 19.1 versions prior to 19.1R3-S6; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R2-S6, 19.3R3-S3; 19.4 versions prior to 19.4R1-S4, 19.4R1-S4, 19.4R3-S3; 20.1 versions prior to 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. This issue does not affect: Juniper Networks Junos OS 12.3 version 12.3R1 and later versions; 15.1 version 15.1R1 and later versions.
