| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2021-04-22 | CVE-2021-0257 | Memory Leak vulnerability in Juniper Junos On Juniper Networks MX Series and EX9200 Series platforms with Trio-based MPCs (Modular Port Concentrators) where Integrated Routing and Bridging (IRB) interfaces are configured and mapped to a VPLS instance or a Bridge-Domain, certain Layer 2 network events at Customer Edge (CE) devices may cause memory leaks in the MPC of Provider Edge (PE) devices which can cause an out of memory condition and MPC restart. | 6.5 |
| 2021-04-22 | CVE-2021-0255 | Improper Privilege Management vulnerability in Juniper Junos A local privilege escalation vulnerability in ethtraceroute of Juniper Networks Junos OS may allow a locally authenticated user with shell access to escalate privileges and write to the local filesystem as root. | 7.8 |
| 2021-04-22 | CVE-2021-0253 | Unspecified vulnerability in Juniper Junos NFX Series devices using Juniper Networks Junos OS are susceptible to a local command execution vulnerability thereby allowing an attacker to elevate their privileges via the Junos Device Management Daemon (JDMD) process. | 7.8 |
| 2021-04-22 | CVE-2021-0252 | Unspecified vulnerability in Juniper Junos NFX Series devices using Juniper Networks Junos OS are susceptible to a local code execution vulnerability thereby allowing an attacker to elevate their privileges via the Junos Device Management Daemon (JDMD) process. | 7.8 |
| 2021-04-22 | CVE-2021-0249 | Classic Buffer Overflow vulnerability in Juniper Junos On SRX Series devices configured with UTM services a buffer overflow vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS may allow an attacker to arbitrarily execute code or commands on the target to take over or otherwise impact the device by sending crafted packets to or through the device. | 9.8 |
| 2021-04-22 | CVE-2021-0247 | Race Condition vulnerability in Juniper Junos A Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) vulnerability in the firewall process (dfwd) of Juniper Networks Junos OS allows an attacker to bypass the firewall rule sets applied to the input loopback filter on any interfaces of a device. | 5.5 |
| 2021-04-22 | CVE-2021-0242 | Allocation of Resources Without Limits or Throttling vulnerability in Juniper Junos A vulnerability due to the improper handling of direct memory access (DMA) buffers on EX4300 switches on Juniper Networks Junos OS allows an attacker sending specific unicast frames to trigger a Denial of Service (DoS) condition by exhausting DMA buffers, causing the FPC to crash and the device to restart. | 6.5 |
| 2021-04-22 | CVE-2021-0241 | Improper Handling of Exceptional Conditions vulnerability in Juniper Junos On Juniper Networks Junos OS platforms configured as DHCPv6 local server or DHCPv6 Relay Agent, Juniper Networks Dynamic Host Configuration Protocol Daemon (JDHCPD) process might crash with a core dump if a specific DHCPv6 packet is received, resulting in a restart of the daemon. | 6.5 |
| 2021-04-22 | CVE-2021-0240 | Improper Handling of Exceptional Conditions vulnerability in Juniper Junos On Juniper Networks Junos OS platforms configured as DHCPv6 local server or DHCPv6 Relay Agent, the Juniper Networks Dynamic Host Configuration Protocol Daemon (JDHCPD) process might crash if a malformed DHCPv6 packet is received, resulting in a restart of the daemon. | 6.5 |
| 2021-04-22 | CVE-2021-0239 | Improper Check for Unusual or Exceptional Conditions vulnerability in Juniper Junos OS Evolved 20.4 In Juniper Networks Junos OS Evolved, receipt of a stream of specific genuine Layer 2 frames may cause the Advanced Forwarding Toolkit (AFT) manager process (Evo-aftmand), responsible for handling Route, Class-of-Service (CoS), Firewall operations within the packet forwarding engine (PFE) to crash and restart, leading to a Denial of Service (DoS) condition. | 6.5 |
