CVE-2018-0002 – MX series, SRX series: Junos OS: Denial of service vulnerability in Flowd on devices with ALG enabled.
https://notcve.org/view.php?id=CVE-2018-0002
On SRX Series and MX Series devices with a Service PIC with any ALG enabled, a crafted TCP/IP response packet processed through the device results in memory corruption leading to a flowd daemon crash. Sustained crafted response packets lead to repeated crashes of the flowd daemon which results in an extended Denial of Service condition. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D60 on SRX series; 12.3X48 versions prior to 12.3X48-D35 on SRX series; 14.1 versions prior to 14.1R9 on MX series; 14.2 versions prior to 14.2R8 on MX series; 15.1X49 versions prior to 15.1X49-D60 on SRX series; 15.1 versions prior to 15.1R5-S8, 15.1F6-S9, 15.1R6-S4, 15.1R7 on MX series; 16.1 versions prior to 16.1R6 on MX series; 16.2 versions prior to 16.2R3 on MX series; 17.1 versions prior to 17.1R2-S4, 17.1R3 on MX series. No other Juniper Networks products or platforms are affected by this issue. En dispositivos de las series SRX y MX con un Service PIC con cualquier ALG habilitado, un paquete de respuesta TCP/IP manipulado procesado por el dispositivo resulta en una corrupción de memoria que provoca que el demonio flowd se cierre de manera inesperada. • http://www.securitytracker.com/id/1040178 https://kb.juniper.net/JSA10829 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-10620 – SRX Series: Antivirus updates are downloaded without verification
https://notcve.org/view.php?id=CVE-2017-10620
Juniper Networks Junos OS on SRX series devices do not verify the HTTPS server certificate before downloading anti-virus updates. This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks. Affected Junos OS releases are: 12.1X46 prior to 12.1X46-D71; 12.3X48 prior to 12.3X48-D55; 15.1X49 prior to 15.1X49-D110; Juniper Networks Junos OS en dispositivos de la serie SRX no verifica el certificado del servidor HTTPS antes de descargar actualizaciones de antivirus. Esto puede permitir que un atacante Man-in-the-Middle (MitM) inyecte firmas falsas para causar disrupciones de servicio o hacer que el dispositivo no detecte ciertos tipos de ataques. Las distribuciones afectadas Junos OS son: 12.1X46 anteriores a 12.1X46-D71; 12.3X48 anteriores a 12.3X48-D55; 15.1X49 anteriores a 15.1X49-D110. • https://kb.juniper.net/JSA10822 • CWE-295: Improper Certificate Validation •
CVE-2017-10619 – Junos: SRX cluster denial of service vulnerability in flowd due to multicast packets
https://notcve.org/view.php?id=CVE-2017-10619
When Express Path (formerly known as service offloading) is configured on Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 in high availability cluster configuration mode, certain multicast packets might cause the flowd process to crash, halting or interrupting traffic from flowing through the device and triggering RG1+ (data-plane) fail-over to the secondary node. Repeated crashes of the flowd process may constitute an extended denial of service condition. This service is not enabled by default and is only supported in high-end SRX platforms. Affected releases are Juniper Networks Junos OS 12.3X48 prior to 12.3X48-D45, 15.1X49 prior to 15.1X49-D80 on SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800. Cuando Express Path (antes conocido como "service offloading") se configura en Juniper Networks SRX1400, SRX3400, SRX3600, SRX5400, SRX5600, SRX5800 en modo de configuración de clústeres en alta disponibilidad, algunos paquetes multicast podrían causar que el proceso flowd se cierre de manera inesperada, deteniendo o interrumpiendo el trafico que atraviesa el dispositivo y desencadenando un fail-over RG1+ (data-plane) en el nodo secundario. • https://kb.juniper.net/JSA10821 •
CVE-2017-10608 – SRX series: Junos OS: SRX series using IPv6 Sun/MS-RPC ALGs may experience flowd crash on processing packets.
https://notcve.org/view.php?id=CVE-2017-10608
Any Juniper Networks SRX series device with one or more ALGs enabled may experience a flowd crash when traffic is processed by the Sun/MS-RPC ALGs. This vulnerability in the Sun/MS-RPC ALG services component of Junos OS allows an attacker to cause a repeated denial of service against the target. Repeated traffic in a cluster may cause repeated flip-flop failure operations or full failure to the flowd daemon halting traffic on all nodes. Only IPv6 traffic is affected by this issue. IPv4 traffic is unaffected. • https://kb.juniper.net/JSA10811 • CWE-400: Uncontrolled Resource Consumption •
CVE-2017-10605 – Junos: SRX Series denial of service vulnerability in flowd due to crafted DHCP packet
https://notcve.org/view.php?id=CVE-2017-10605
On all vSRX and SRX Series devices, when the DHCP or DHCP relay is configured, specially crafted packet might cause the flowd process to crash, halting or interrupting traffic from flowing through the device(s). Repeated crashes of the flowd process may constitute an extended denial of service condition for the device(s). If the device is configured in high-availability, the RG1+ (data-plane) will fail-over to the secondary node. If the device is configured in stand-alone, there will be temporary traffic interruption until the flowd process is restored automatically. Sustained crafted packets may cause the secondary failover node to fail back, or fail completely, potentially halting flowd on both nodes of the cluster or causing flip-flop failovers to occur. • http://www.securitytracker.com/id/1038891 https://kb.juniper.net/JSA10789 • CWE-20: Improper Input Validation •
