CVSS: 7.5EPSS: 0%CPEs: 301EXPL: 0CVE-2019-0068 – Junos OS: SRX Series: Denial of Service vulnerability in flowd due to multicast packets
https://notcve.org/view.php?id=CVE-2019-0068
The SRX flowd process, responsible for packet forwarding, may crash and restart when processing specific multicast packets. By continuously sending the specific multicast packets, an attacker can repeatedly crash the flowd process causing a sustained Denial of Service. This issue affects Juniper Networks Junos OS on SRX Series: 12.3X48 versions prior to 12.3X48-D90; 15.1X49 versions prior to 15.1X49-D180; 17.3 versions; 17.4 versions prior to 17.4R2-S5, 17.4R3; 18.1 versions prior to 18.1R3-S6; 18.2 versions prior to 18.2R2-S4, 18.2R3; 18.3 versions prior to 18.3R2-S1, 18.3R3; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R1-S1, 19.1R2. El proceso flowd SRX, responsable del reenvío de paquetes, puede bloquearse y reiniciarse cuando se procesan paquetes de multidifusión específicos. Mediante el envío de manera continua de los paquetes de multidifusión específicos, un atacante puede bloquear repetidamente el proceso flowd causando una Denegación de Servicio sostenida. • https://kb.juniper.net/JSA10968 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 6.5EPSS: 0%CPEs: 29EXPL: 0CVE-2019-0067 – Junos OS: Kernel crash (vmcore) upon receipt of a specific link-local IPv6 packet on devices configured with Multi-Chassis Link Aggregation Group (MC-LAG)
https://notcve.org/view.php?id=CVE-2019-0067
Receipt of a specific link-local IPv6 packet destined to the RE may cause the system to crash and restart (vmcore). By continuously sending a specially crafted IPv6 packet, an attacker can repeatedly crash the system causing a prolonged Denial of Service (DoS). This issue affects Juniper Networks Junos OS: 16.1 versions prior to 16.1R6-S2, 16.1R7; 16.2 versions prior to 16.2R2-S10; 17.1 versions prior to 17.1R3. This issue does not affect Juniper Networks Junos OS version 15.1 and prior versions. La recepción de un paquete específico IPv6 de enlace local destinado al RE puede hacer que el sistema se bloquee y reinicie (vmcore). • https://kb.juniper.net/JSA10966 •
CVSS: 7.5EPSS: 0%CPEs: 132EXPL: 0CVE-2019-0066 – Junos OS: A malformed IPv4 packet received by Junos in an NG-mVPN scenario may cause the routing protocol daemon (rpd) process to core
https://notcve.org/view.php?id=CVE-2019-0066
An unexpected status return value weakness in the Next-Generation Multicast VPN (NG-mVPN) service of Juniper Networks Junos OS allows attacker to cause a Denial of Service (DoS) condition and core the routing protocol daemon (rpd) process when a specific malformed IPv4 packet is received by the device running BGP. This malformed packet can be crafted and sent to a victim device including when forwarded directly through a device receiving such a malformed packet, but not if the malformed packet is first de-encapsulated from an encapsulated format by a receiving device. Continued receipt of the malformed packet will result in a sustained Denial of Service condition. This issue affects: Juniper Networks Junos OS 15.1 versions prior to 15.1F6-S12, 15.1R7-S2; 15.1X49 versions prior to 15.1X49-D150 on SRX Series; 15.1X53 versions prior to 15.1X53-D68, 15.1X53-D235, 15.1X53-D495, 15.1X53-D590; 16.1 versions prior to 16.1R3-S10, 16.1R4-S12, 16.1R6-S6, 16.1R7-S2; 16.2 versions prior to 16.2R2-S7; 17.1 versions prior to 17.1R2-S9, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R2-S6, 17.2R3; 17.3 versions prior to 17.3R2-S4, 17.3R3. Una debilidad de valor de retorno de estado inesperado en el Next-Generation Multicast VPN (NG-mVPN) de Juniper Networks Junos OS, permite al atacante causar una condición de denegación de servicio (DoS) y centrar el proceso del demonio del protocolo de enrutamiento (rpd) cuando un paquete IPv4 malformado específico es recibido por parte del dispositivo que ejecuta BGP. • https://kb.juniper.net/JSA10965 https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/ng-mvpn-services-enabling.html • CWE-394: Unexpected Status Code or Return Value •
CVSS: 7.5EPSS: 0%CPEs: 259EXPL: 0CVE-2019-0065 – Junos OS: MX Series: Denial of Service vulnerability in MS-PIC component on MS-MIC or MS-MPC
https://notcve.org/view.php?id=CVE-2019-0065
On MX Series, when the SIP ALG is enabled, receipt of a certain malformed SIP packet may crash the MS-PIC component on MS-MIC or MS-MPC. By continuously sending a crafted SIP packet, an attacker can repeatedly bring down MS-PIC on MS-MIC/MS-MPC causing a sustained Denial of Service. This issue affects Juniper Networks Junos OS on MX Series: 16.1 versions prior to 16.1R7-S5; 16.2 versions prior to 16.2R2-S11; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3-S3; 17.3 versions prior to 17.3R3-S6 ; 17.4 versions prior to 17.4R2-S8, 17.4R3; 18.1 versions prior to 18.1R3-S3; 18.2 versions prior to 18.2R3; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2. En la serie MX, cuando el ALG SIP está habilitado, la recepción de un paquete SIP malformado puede bloquear el componente MS-PIC en MS-MIC o MS-MPC. Mediante el envío de manera continua de un paquete SIP diseñado, un atacante puede derribar repetidamente MS-PIC sobre MS-MIC/MS-MPC causando una Denegación de Servicio sostenida. • https://kb.juniper.net/JSA10964 •
CVSS: 7.5EPSS: 0%CPEs: 340EXPL: 0CVE-2019-0063 – Junos OS: MX Series: jdhcpd crash when receiving a specific crafted DHCP response message
https://notcve.org/view.php?id=CVE-2019-0063
When an MX Series Broadband Remote Access Server (BRAS) is configured as a Broadband Network Gateway (BNG) with DHCPv6 enabled, jdhcpd might crash when receiving a specific crafted DHCP response message on a subscriber interface. The daemon automatically restarts without intervention, but continuous receipt of specific crafted DHCP messages will repeatedly crash jdhcpd, leading to an extended Denial of Service (DoS) condition. This issue only affects systems configured with DHCPv6 enabled. DHCPv4 is unaffected by this issue. This issue affects Juniper Networks Junos OS: 15.1 versions prior to 15.1R7-S5 on MX Series; 16.1 versions prior to 16.1R7-S5 on MX Series; 16.2 versions prior to 16.2R2-S10 on MX Series; 17.1 versions prior to 17.1R3-S1 on MX Series; 17.2 versions prior to 17.2R3-S2 on MX Series; 17.3 versions prior to 17.3R3-S6 on MX Series; 17.4 versions prior to 17.4R2-S5, 17.4R3 on MX Series; 18.1 versions prior to 18.1R3-S6 on MX Series; 18.2 versions prior to 18.2R2-S4, 18.2R3 on MX Series; 18.2X75 versions prior to 18.2X75-D50 on MX Series; 18.3 versions prior to 18.3R1-S5, 18.3R3 on MX Series; 18.4 versions prior to 18.4R2 on MX Series; 19.1 versions prior to 19.1R1-S2, 19.1R2 on MX Series. • https://kb.juniper.net/JSA10962 •
