Vulnerability from gsd
Modified
2023-12-13 01:20
Details
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). Continued receipt and processing of telemetry requests will repeatedly crash the jkdsd process and sustain the Denial of Service (DoS) condition.
This issue is seen on all Junos platforms. The crash is triggered when multiple telemetry requests come from different collectors. As the load increases, the Dynamic Rendering Daemon (drend) decides to defer processing and continue later, which results in a timing issue accessing stale memory, causing the jkdsd process to crash and restart.
Note: jkdsd is not shipped with SRX Series devices and therefore are not affected by this vulnerability.
This issue affects:
Juniper Networks Junos OS:
* 20.4 versions prior to 20.4R3-S9;
* 21.1 versions 21.1R1 and later;
* 21.2 versions prior to 21.2R3-S6;
* 21.3 versions prior to 21.3R3-S5;
* 21.4 versions prior to 21.4R3-S5;
* 22.1 versions prior to 22.1R3-S4;
* 22.2 versions prior to 22.2R3-S2;
* 22.3 versions prior to 22.3R2-S1, 22.3R3-S1;
* 22.4 versions prior to 22.4R2-S2, 22.4R3;
* 23.1 versions prior to 23.1R2;
* 23.2 versions prior to 23.2R2.
This issue does not affect Juniper Networks Junos OS versions prior to 19.4R1.

"value": "\nA 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). Continued receipt and processing of telemetry requests will repeatedly crash the jkdsd process and sustain the Denial of Service (DoS) condition.\n\nThis issue is seen on all Junos platforms. The crash is triggered when multiple telemetry requests come from different collectors. As the load increases, the Dynamic Rendering Daemon (drend) decides to defer processing and continue later, which results in a timing issue accessing stale memory, causing the jkdsd process to crash and restart.\n\nNote: jkdsd is not shipped with SRX Series devices and therefore are not affected by this vulnerability.\nThis issue affects:\n\nJuniper Networks Junos OS:\n\n\n\n * 20.4 versions prior to 20.4R3-S9;\n * 21.1 versions 21.1R1 and later;\n * 21.2 versions prior to 21.2R3-S6;\n * 21.3 versions prior to 21.3R3-S5;\n * 21.4 versions prior to 21.4R3-S5;\n * 22.1 versions prior to 22.1R3-S4;\n * 22.2 versions prior to 22.2R3-S2;\n * 22.3 versions prior to 22.3R2-S1, 22.3R3-S1;\n * 22.4 versions prior to 22.4R2-S2, 22.4R3;\n * 23.1 versions prior to 23.1R2.\n\n\n\n\nThis issue does not affect Juniper Networks Junos OS versions prior to 19.4R1.\n\n\n\n"

La recepci\u00f3n y el procesamiento continuo de solicitudes de telemetr\u00eda bloquear\u00e1n repetidamente el proceso jkdsd y mantendr\u00e1n la condici\u00f3n de Denegaci\u00f3n de Servicio (DoS). Este problema se observa en todas las plataformas Junos. El bloqueo se desencadena cuando varias solicitudes de telemetr\u00eda provienen de diferentes recopiladores. A medida que aumenta la carga, el Dynamic Rendering Daemon (drend) decide posponer el procesamiento y continuar m\u00e1s tarde, lo que genera un problema de sincronizaci\u00f3n al acceder a la memoria obsoleta, lo que provoca que el proceso jkdsd falle y se reinicie. Nota: jkdsd no se env\u00eda con los dispositivos de la serie SRX y, por lo tanto, no se ve afectado por esta vulnerabilidad. Este problema afecta a: Juniper Networks Junos OS: * Versiones 20.4 anteriores a 20.4R3-S9; * 21.1 versiones 21.1R1 y posteriores; * Versiones 21.2 anteriores a 21.2R3-S6; * Versiones 21.3 anteriores a 21.3R3-S5; * Versiones 21.4 anteriores a 21.4R3-S5; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3-S2; * Versiones 22.3 anteriores a 22.3R2-S1, 22.3R3-S1; * Versiones 22.4 anteriores a 22.4R2-S2, 22.4R3; * Versiones 23.1 anteriores a 23.1R2; * Versiones 23.2 anteriores a 23.2R2.
