|---|---|---|---|
| 2023-10-13 | CVE-2023-44199 | Improper Check for Unusual or Exceptional Conditions vulnerability in Juniper Junos An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX Series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). On Junos MX Series platforms with Precision Time Protocol (PTP) configured, a prolonged routing protocol churn can lead to an FPC crash and restart. This issue affects Juniper Networks Junos OS on MX Series: * All versions prior to 20.4R3-S4; * 21.1 version 21.1R1 and later versions; * 21.2 versions prior to 21.2R3-S2; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3; * 22.1 versions prior to 22.1R3; * 22.2 versions prior to 22.2R1-S1, 22.2R2. | 7.5 |
| 2023-10-13 | CVE-2023-44201 | Incorrect Permission Assignment for Critical Resource vulnerability in Juniper Junos An Incorrect Permission Assignment for Critical Resource vulnerability in a specific file of Juniper Networks Junos OS and Junos OS Evolved allows a local authenticated attacker to read configuration changes without having the permissions. When a user with the respective permissions commits a configuration change, a specific file is created. | 5.5 |
| 2023-10-13 | CVE-2023-44203 | Unspecified vulnerability in Juniper Junos An Improper Check or Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600 allows a adjacent attacker to send specific traffic, which leads to packet flooding, resulting in a Denial of Service (DoS). When a specific IGMP packet is received in an isolated VLAN, it is duplicated to all other ports under the primary VLAN, which causes a flood. This issue affects QFX5000 series, EX2300, EX3400, EX4100, EX4400 and EX4600 platforms only. This issue affects Juniper Junos OS on on QFX5000 Series, EX2300, EX3400, EX4100, EX4400 and EX4600: * All versions prior to 20.4R3-S5; * 21.1 versions prior to 21.1R3-S4; * 21.2 versions prior to 21.2R3-S3; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S2; * 22.1 versions prior to 22.1R3; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R2. low complexity juniper | 6.5 |
| 2023-10-12 | CVE-2023-22392 | Memory Leak vulnerability in Juniper Junos A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an adjacent, unauthenticated attacker to cause a Denial of Service (DoS). PTX3000, PTX5000, QFX10000, PTX1000, PTX10002, and PTX10004, PTX10008 and PTX10016 with LC110x FPCs do not support certain flow-routes. | 6.5 |
| 2023-10-12 | CVE-2023-36839 | Improper Validation of Specified Quantity in Input vulnerability in Juniper Junos An Improper Validation of Specified Quantity in Input vulnerability in the Layer-2 control protocols daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker who sends specific LLDP packets to cause a Denial of Service(DoS). This issue occurs when specific LLDP packets are received and telemetry polling is being done on the device. | 6.5 |
| 2023-10-12 | CVE-2023-36841 | Resource Exhaustion vulnerability in Juniper Junos An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS on MX Series allows a unauthenticated network-based attacker to cause an infinite loop, resulting in a Denial of Service (DoS). An attacker who sends malformed TCP traffic via an interface configured with PPPoE, causes an infinite loop on the respective PFE. | 7.5 |
| 2023-10-12 | CVE-2023-36843 | Unspecified vulnerability in Juniper Junos An Improper Handling of Inconsistent Special Elements vulnerability in the Junos Services Framework (jsf) module of Juniper Networks Junos OS allows an unauthenticated network based attacker to cause a crash in the Packet Forwarding Engine (pfe) and thereby resulting in a Denial of Service (DoS). Upon receiving malformed SSL traffic, the PFE crashes. | 7.5 |
| 2023-10-12 | CVE-2023-44175 | Reachable Assertion vulnerability in Juniper Junos A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows to send specific genuine PIM packets to the device resulting in rpd to crash causing a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Note: This issue is not noticed when all the devices in the network are Juniper devices. This issue affects Juniper Networks: Junos OS: * All versions prior to 20.4R3-S7; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R3; * 22.4 versions prior to 22.4R3. Junos OS Evolved: * All versions prior to 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R3-EVO; * 23.2-EVO versions prior to 23.2R1-EVO. | 7.5 |
| 2023-10-11 | CVE-2023-44186 | Improper Handling of Exceptional Conditions vulnerability in Juniper Junos An Improper Handling of Exceptional Conditions vulnerability in AS PATH processing of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a BGP update message with an AS PATH containing a large number of 4-byte ASes, leading to a Denial of Service (DoS). | 7.5 |
| 2023-10-11 | CVE-2023-44188 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Juniper Junos A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in telemetry processing of Juniper Networks Junos OS allows a network-based authenticated attacker to flood the system with multiple telemetry requests, causing the Junos Kernel Debugging Streaming Daemon (jkdsd) process to crash, leading to a Denial of Service (DoS). | 5.3 |
