DescriptionCVE.org

An Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).

When a high amount of specific traffic is received on a SRX4600 device, due to an error in internal packet handling, a consistent rise in CPU memory utilization occurs. This results in packet drops in the traffic and eventually the PFE crashes. A manual reboot of the PFE will be required to restore the device to original state.

This issue affects Junos OS:

  • 21.2 before 21.2R3-S7,
  • 21.4 before 21.4R3-S6,
  • 22.1 before 22.1R3-S5,
  • 22.2 before 22.2R3-S3,
  • 22.3 before 22.3R3-S2,
  • 22.4 before 22.4R3,
  • 23.2 before 23.2R1-S2, 23.2R2.

Technical ContextAI

This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. An Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When a high amount of specific traffic is received on a SRX4600 device, due to an error in internal packet handling, a consistent rise in CPU memory utilization occurs. This results in packet drops in the traffic and eventually the PFE crashes. A manual reboot of the PFE will be required to restore the device to original state.2 before 21.2R3-S7, * 21.4 before 21.4R3-S6, * 22.1 before 22.1R3-S5, * 22.2 before 22.2R3-S3, * 22.3 before 22.3R3-S2, * 22.4 before 22.4R3, * 23.2 before 23.2R1-S2, 23.2R2. Affected products include: Juniper Junos. Version information: before 21.2.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.
