CVE-2024-39560 – Junos OS and Junos OS Evolved: Memory leak due to RSVP neighbor persistent error leading to kernel crash
https://notcve.org/view.php?id=CVE-2024-39560
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent downstream RSVP neighbor to cause kernel memory exhaustion, leading to a kernel crash, resulting in a Denial of Service (DoS). The kernel memory leak and eventual crash will be seen when the downstream RSVP neighbor has a persistent error which will not be corrected. System kernel memory can be monitored through the use of the 'show system statistics kernel memory' command as shown below: user@router> show system statistics kernel memory Memory Size (kB) Percentage When Active 753092 18.4% Now Inactive 574300 14.0% Now Wired 443236 10.8% Now Cached 1911204 46.6% Now Buf 32768 0.8% Now Free 385072 9.4% Now Kernel Memory Now Data 312908 7.6% Now Text 2560 0.1% Now ...

Una vulnerabilidad de manejo inadecuado de condiciones excepcionales en el daemon del protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un vecino RSVP descendente lógicamente adyacente provoque el agotamiento de la memoria del kernel, lo que provoca un fallo del kernel, lo que resulta en una denegación de servicio ( DoS). La pérdida de memoria del kernel y su eventual fallo se verán cuando el vecino RSVP descendente tenga un error persistente que no se corregirá. ...

CVE-2024-39559 – Junos OS Evolved: Receipt of a specific TCP packet may result in a system crash (vmcore) on dual RE systems with NSR enabled
https://notcve.org/view.php?id=CVE-2024-39559
An Improper Check for Unusual or Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS Evolved may allow a network-based unauthenticated attacker to crash the device (vmcore) by sending a specific TCP packet over an established TCP session with MD5 authentication enabled, destined to an accessible port on the device, resulting in a Denial of Service (DoS). The receipt of this packet must occur within a specific timing window outside the attacker's control (i.e., race condition). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects dual RE systems with Nonstop Active Routing (NSR) enabled. Exploitation can only occur over TCP sessions with MD5 authentication enabled (e.g., BGP with MD5 authentication). This issue affects Junos OS Evolved: * All versions before 21.2R3-S8-EVO, * from 21.4-EVO before 21.4R3-S6-EVO, * from 22.1-EVO before 22.1R3-S4-EVO, * from 22.2-EVO before 22.2R3-S4-EVO, * from 22.3-EVO before 22.3R3-S3-EVO, * from 22.4-EVO before 22.4R2-S2-EVO, 22.4R3-EVO. ... La recepción de este paquete debe ocurrir dentro de una ventana de tiempo específica fuera del control del atacante (es decir, condición de ejecución). La recepción y procesamiento continuo de este paquete creará una condición sostenida de Denegación de Servicio (DoS). Este problema solo afecta a los sistemas RE duales con el enrutamiento activo ininterrumpido (NSR) habilitado. • https://supportportal.juniper.net/JSA83019 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
