18 Oct 2022 — An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX7000 Series allows an unauthenticated network-based attacker to cause a partial Denial of Service (DoS). On receipt of specific IPv6 transit traffic, Junos OS Evolved on ACX7100-48L, ACX7100-32C and ACX7509 sends this traffic to the Routing Engine (RE) instead of forwarding it, leading to increased CPU utilization of the RE and a partial DoS. This issue only ... • https://kb.juniper.net/JSA69878 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

18 Oct 2022 — A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated attacker with an established BGP session to cause a Denial of Service (DoS). In a BGP multipath scenario, when one of the contributing routes is flapping often and rapidly, rpd may crash. As this crash depends on whether a route is a contributing route, and on the internal timing of the events triggered by the flap this vulnerabili... • https://kb.juniper.net/JSA69875 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

18 Oct 2022 — An Improper Check or Handling of Exceptional Conditions vulnerability in the processing of a malformed OSPF TLV in Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated adjacent attacker to cause the periodic packet management daemon (PPMD) process to go into an infinite loop, which in turn can cause protocols and functions reliant on PPMD such as OSPF neighbor reachability to be impacted, resulting in a sustained Denial of Service (DoS) condition. The DoS condition persists until the PPM... • https://kb.juniper.net/JSA69874 • CWE-703: Improper Check or Handling of Exceptional Conditions •

18 Oct 2022 — A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS, Junos OS Evolved allows a network-based unauthenticated attacker to cause a Denial of Service (DoS). When a BGP flow route with redirect IP extended community is received, and the reachability to the next-hop of the corresponding redirect IP is flapping, the rpd process might crash. Whether the crash occurs depends on the timing of the internally processing of these two events and... • https://kb.juniper.net/JSA69902 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

18 Oct 2022 — A limitless resource allocation vulnerability in FPC resources of Juniper Networks Junos OS Evolved on PTX Series allows an unprivileged attacker to cause Denial of Service (DoS). Continuously polling the SNMP jnxCosQstatTable causes the FPC to run out of GUID space, causing a Denial of Service to the FPC resources. When the FPC runs out of the GUID space, you will see the following syslog messages. The evo-aftmand-bt process is asserting. fpc1 evo-aftmand-bt[17556]: %USER-3: get_next_guid: Ran out of Guid ... • https://kb.juniper.net/JSA69916 • CWE-770: Allocation of Resources Without Limits or Throttling •

18 Oct 2022 — A Use After Free vulnerability in the Routing Protocol Daemon (rdp) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated network-based attacker to cause Denial of Service (DoS). When a BGP session flap happens, a Use After Free of a memory location that was assigned to another object can occur, which will lead to an rpd crash. This is a race condition that is outside of the attacker's control and cannot be deterministically exploited. Continued flapping of BGP sessions can create a su... • https://kb.juniper.net/JSA69879 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

18 Oct 2022 — An Improper Validation of Syntactic Correctness of Input vulnerability in the kernel of Juniper Networks Junos OS Evolved on PTX series allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). When an incoming TCP packet destined to the device is malformed there is a possibility of a kernel panic. Only TCP packets destined to the ports for BGP, LDP and MSDP can trigger this. This issue only affects PTX10004, PTX10008, PTX10016. No other PTX Series devices or other platforms are a... • https://kb.juniper.net/JSA69915 • CWE-20: Improper Input Validation CWE-1286: Improper Validation of Syntactic Correctness of Input •

20 Jul 2022 — A Missing Release of File Descriptor or Handle after Effective Lifetime vulnerability in plugable authentication module (PAM) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). It is possible that after the termination of a gRPC connection the respective/var/run/.env file is not getting deleted which if occurring repeatedly can cause inode exhaustion. Inode exhaustion can present itself in two different ways:... • https://kb.juniper.net/JSA69719 • CWE-772: Missing Release of Resource after Effective Lifetime •

20 Jul 2022 — An Improper Input Validation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent attacker to cause a PFE crash and thereby a Denial of Service (DoS). An FPC will crash and reboot after receiving a specific transit IPv6 packet over MPLS. Continued receipt of this packet will create a sustained Denial of Service (DoS) condition. This issue does not affect systems configured for IPv4 only. This issue affects: Juniper Networks Junos OS All ver... • https://kb.juniper.net/JSA69718 • CWE-20: Improper Input Validation •

20 Jul 2022 — A vulnerability in Handling of Undefined Values in the routing protocol daemon (RPD) process of Juniper Networks Junos OS and Junos OS Evolved may allow an unauthenticated network-based attacker to crash the RPD process by sending a specific BGP update while the system is under heavy load, leading to a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Malicious exploitation of this issue requires a very specific combination of... • https://kb.juniper.net/JSA69717 • CWE-232: Improper Handling of Undefined Values •
