Vulnerability from fkie_nvd - Published: 2025-04-09 20:15 - Updated: 2025-04-11 15:40
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A Missing Release of Memory after Effective Lifetime vulnerability in the Anti-Virus processing of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). On all SRX platforms with Anti-Virus enabled, if a server sends specific content in the HTTP body of a response to a client request, these packets are queued by Anti-Virus processing in Juniper Buffers (jbufs) which are never released. When these jbufs are exhausted, the device stops forwarding all transit traffic. A jbuf memory leak can be noticed from the following logs: (<node>.)<fpc> Warning: jbuf pool id <#> utilization level (<current level>%) is above <threshold>%! To recover from this issue, the affected device needs to be manually rebooted to free the leaked jbufs. This issue affects Junos OS on SRX Series:  * all versions before 21.2R3-S9, * 21.4 versions before 21.4R3-S10, * 22.2 versions before 22.2R3-S6, * 22.4 versions before 22.4R3-S6, * 23.2 versions before 23.2R2-S3, * 23.4 versions before 23.4R2-S3, * 24.2 versions before 24.2R2.

En todas las plataformas SRX con antivirus habilitado, si un servidor env\u00eda contenido espec\u00edfico en el cuerpo HTTP de una respuesta a una solicitud de cliente, estos paquetes se almacenan en cola mediante el procesamiento antivirus en los b\u00faferes de Juniper (jbufs), que nunca se liberan. Cuando estos jbufs se agotan, el dispositivo deja de reenviar todo el tr\u00e1fico de tr\u00e1nsito. Se puede observar una fuga de memoria jbuf en los siguientes registros: (.) Advertencia: el nivel de utilizaci\u00f3n del id del grupo de jbufs \u0026lt;#\u0026gt; (%) es superior al %. Para solucionar este problema, es necesario reiniciar manualmente el dispositivo afectado para liberar los jbufs filtrados. Este problema afecta a Junos OS en la serie SRX: * todas las versiones anteriores a 21.2R3-S9, * versiones 21.4 anteriores a 21.4R3-S10, * versiones 22.2 anteriores a 22.2R3-S6, * versiones 22.4 anteriores a 22.4R3-S6, * versiones 23.2 anteriores a 23.2R2-S3, * versiones 23.4 anteriores a 23.4R2-S3, * versiones 24.2 anteriores a 24.2R2."
