CVSS: 7.5EPSS: 1%CPEs: 75EXPL: 0CVE-2019-0001 – Junos OS: MX Series: uncontrolled recursion and crash in Broadband Edge subscriber management daemon (bbe-smgd).
https://notcve.org/view.php?id=CVE-2019-0001
Receipt of a malformed packet on MX Series devices with dynamic vlan configuration can trigger an uncontrolled recursion loop in the Broadband Edge subscriber management daemon (bbe-smgd), and lead to high CPU usage and a crash of the bbe-smgd service. Repeated receipt of the same packet can result in an extended denial of service condition for the device. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S1; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S1; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2. La recepción de un paquete mal formado en dispositivos MX Series con una configuración vlan dinámica puede desencadenar un bucle de recursión no controlado en el demonio de gestión de suscriptores Broadband Edge (bbe-smgd) y conducir a un alto uso de CPU y el cierre inesperado del servicio bbe-smgd. La recepción repetida del mismo paquete puede resultar en una condición de denegación de servicio (DoS) extendida para los dispositivos. • http://www.securityfocus.com/bid/106541 https://kb.juniper.net/JSA10900 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RMKFSHPMOZL7MDWU5RYOTIBTRWSZ4Z6X https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/W7CPKBW4QZ4VIY4UXIUVUSHRJ4R2FROE • CWE-674: Uncontrolled Recursion •
CVSS: 5.5EPSS: 0%CPEs: 14EXPL: 0CVE-2019-0009 – Junos OS: EX2300 and EX3400: High disk I/O operations may disrupt the communication between RE and PFE
https://notcve.org/view.php?id=CVE-2019-0009
On EX2300 and EX3400 series, high disk I/O operations may disrupt the communication between the routing engine (RE) and the packet forwarding engine (PFE). In a virtual chassis (VC) deployment, this issue disrupts communication between the VC members. This issue does not affect other Junos platforms. Affected releases are Junos OS on EX2300 and EX3400 series: 15.1X53 versions prior to 15.1X53-D590; 18.1 versions prior to 18.1R2-S2, 18.1R3; 18.2 versions prior to 18.2R2. En las series EX2300 y EX3400, las operaciones high disk I/O podrían interrumpir las comunicaciones entre el motor de enrutamiento (RE) y el motor de reenvío de paquetes (PFE). • http://www.securityfocus.com/bid/106548 https://kb.juniper.net/JSA10909 •
CVSS: 9.8EPSS: 0%CPEs: 20EXPL: 0CVE-2019-0002 – Junos OS: EX2300 and EX3400 series: Certain stateless firewall filter rules might not take effect
https://notcve.org/view.php?id=CVE-2019-0002
On EX2300 and EX3400 series, stateless firewall filter configuration that uses the action 'policer' in combination with other actions might not take effect. When this issue occurs, the output of the command: show pfe filter hw summary will not show the entry for: RACL group Affected releases are Junos OS on EX2300 and EX3400 series: 15.1X53 versions prior to 15.1X53-D590; 18.1 versions prior to 18.1R3; 18.2 versions prior to 18.2R2. This issue affect both IPv4 and IPv6 firewall filter. En las series EX2300 y EX3400, la configuración sin estado del filtro del firewall que emplea la acción "policer" junto con otras acciones podría no aplicarse. Cuando este problema ocurre, el resultado del comando show pfe filter hw summary no mostrará la entrada para: RACL group. • http://www.securityfocus.com/bid/106669 https://kb.juniper.net/JSA10901 https://www.juniper.net/documentation/en_US/junos/topics/reference/command-summary/show-pfe-filter.html • CWE-794: Incomplete Filtering of Multiple Instances of Special Elements •

On EX2300, EX3400, EX4600, QFX3K and QFX5K series, firewall filter configuration cannot perform packet matching on any IPv6 extension headers. This issue may allow IPv6 packets that should have been blocked to be forwarded. IPv4 packet filtering is unaffected by this vulnerability. Affected releases are Juniper Networks Junos OS on EX and QFX series;: 14.1X53 versions prior to 14.1X53-D47; 15.1 versions prior to 15.1R7; 15.1X53 versions prior to 15.1X53-D234 on QFX5200/QFX5110 series; 15.1X53 versions prior to 15.1X53-D591 on EX2300/EX3400 series; 16.1 versions prior to 16.1R7; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3; 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2.

CVSS: 6.5EPSS: 0%CPEs: 27EXPL: 0CVE-2019-0011 – Junos OS: Kernel crash after processing specific incoming packet to the out of band management interface (CVE-2019-0011)
https://notcve.org/view.php?id=CVE-2019-0011
The Junos OS kernel crashes after processing a specific incoming packet to the out of band management interface (such as fxp0, me0, em0, vme0) destined for another address. By continuously sending this type of packet, an attacker can repeatedly crash the kernel causing a sustained Denial of Service. Affected releases are Juniper Networks Junos OS: 17.2 versions prior to 17.2R1-S7, 17.2R3; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S4, 17.4R2; 17.2X75 versions prior to 17.2X75-D110; 18.1 versions prior to 18.1R2. El kernel de Junos OS se cierra inesperadamente tras procesar un paquete entrante en concreto a la interfaz de gestión de banda (como fxp0, me0, em0, vme0) destinada a otra dirección. Mediante el envío continuo de este tipo de paquete, un atacante puede cerrar repetidamente el kernel, provocando una denegación de servicio (DoS) prolongada. • http://www.securityfocus.com/bid/106534 https://kb.juniper.net/JSA10911 •
