CVSS: 7.5EPSS: 0%CPEs: 17EXPL: 0CVE-2019-0033 – SRX Series: A remote attacker may cause a high CPU Denial of Service to the device when proxy ARP is configured.
https://notcve.org/view.php?id=CVE-2019-0033
A firewall bypass vulnerability in the proxy ARP service of Juniper Networks Junos OS allows an attacker to cause a high CPU condition leading to a Denial of Service (DoS). This issue affects only IPv4. Affected releases are Juniper Networks Junos OS: 12.1X46 versions above and including 12.1X46-D25 prior to 12.1X46-D71, 12.1X46-D73 on SRX Series; 12.3X48 versions prior to 12.3X48-D50 on SRX Series; 15.1X49 versions prior to 15.1X49-D75 on SRX Series. Una vulnerabilidad de omisión del firewall en el servicio ARP proxy del Juniper Networks Junos OS permite a un atacante provocar una condición de denegación de servicio (DoS), debido a un alto uso de la CPU . Este problema afecta sólo a IPv4. • http://www.securityfocus.com/bid/107882 https://kb.juniper.net/JSA10922 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-0031 – Junos OS: jdhcpd daemon memory consumption Denial of Service when receiving specific IPv6 DHCP packets.
https://notcve.org/view.php?id=CVE-2019-0031
Specific IPv6 DHCP packets received by the jdhcpd daemon will cause a memory resource consumption issue to occur on a Junos OS device using the jdhcpd daemon configured to respond to IPv6 requests. Once started, memory consumption will eventually impact any IPv4 or IPv6 request serviced by the jdhcpd daemon, thus creating a Denial of Service (DoS) condition to clients requesting and not receiving IP addresses. Additionally, some clients which were previously holding IPv6 addresses will not have their IPv6 Identity Association (IA) address and network tables agreed upon by the jdhcpd daemon after the failover event occurs, which leads to more than one interface, and multiple IP addresses, being denied on the client. Affected releases are Juniper Networks Junos OS: 17.4 versions prior to 17.4R2; 18.1 versions prior to 18.1R2. Los paquetes DHCP IPv6 específicos recibidos por el demonio jdhcpd causarán un problema de consumo de recursos de memoria en un dispositivo Junos OS que utiliza el demonio jdhcpd configurado para responder a las peticiones de IPv6. • http://www.securityfocus.com/bid/107874 https://kb.juniper.net/JSA10920 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 0%CPEs: 56EXPL: 0CVE-2019-0028 – Junos OS: RPD process crashes due to specific BGP peer restarts condition.
https://notcve.org/view.php?id=CVE-2019-0028
On Junos devices with the BGP graceful restart helper mode enabled or the BGP graceful restart mechanism enabled, a BGP session restart on a remote peer that has the graceful restart mechanism enabled may cause the local routing protocol daemon (RPD) process to crash and restart. By simulating a specific BGP session restart, an attacker can repeatedly crash the RPD process causing prolonged denial of service (DoS). Graceful restart helper mode for BGP is enabled by default. No other Juniper Networks products or platforms are affected by this issue. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7; 16.1X65 versions prior to 16.1X65-D48; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S7, 17.1R3; 17.2 versions prior to 17.2R1-S7, 17.2R3; 17.2X75 versions prior to 17.2X75-D92, 17.2X75-D102, 17.2X75-D110; 17.3 versions prior to 17.3R2-S2, 17.3R3; 17.4 versions prior to 17.4R1-S4, 17.4R2; 18.1 versions prior to 18.1R2. • http://www.securityfocus.com/bid/107892 https://kb.juniper.net/JSA10932 • CWE-404: Improper Resource Shutdown or Release •
CVSS: 7.5EPSS: 0%CPEs: 39EXPL: 0CVE-2019-0019 – BGP packets can trigger rpd crash when BGP tracing is enabled.
https://notcve.org/view.php?id=CVE-2019-0019
When BGP tracing is enabled an incoming BGP message may cause the Junos OS routing protocol daemon (rpd) process to crash and restart. While rpd restarts after a crash, repeated crashes can result in an extended DoS condition. Affected releases are Juniper Networks Junos OS: 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9, 16.2R3; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3-S1; 17.3 versions prior to 17.3R3-S3, 17.3R3-S4, 17.3R4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3, 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4, 18.1R4; 18.2 versions prior to 18.2R2-S2, 18.2R2-S3, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. This issue does not affect Junos releases prior to 16.1R1. Cuando la función de rastreo BGP (Border Gateway Protocol) está activada, un mensaje BGP entrante puede provocar que el proceso rpd (Routing Protocol Daemon) del Junos OS se cierre inesperadamente y se reinicie. • http://www.securityfocus.com/bid/107893 https://kb.juniper.net/JSA10931 • CWE-404: Improper Resource Shutdown or Release •
CVSS: 9.8EPSS: 6%CPEs: 23EXPL: 0CVE-2019-0008 – QFX5000 Series, EX4300, EX4600: A stack buffer overflow vulnerability in Packet Forwarding Engine manager (FXPC) process
https://notcve.org/view.php?id=CVE-2019-0008
A certain sequence of valid BGP or IPv6 BFD packets may trigger a stack based buffer overflow in the Junos OS Packet Forwarding Engine manager (FXPC) process on QFX5000 series, EX4300, EX4600 devices. This issue can result in a crash of the fxpc daemon or may potentially lead to remote code execution. Affected releases are Juniper Networks Junos OS on QFX 5000 series, EX4300, EX4600 are: 14.1X53; 15.1X53 versions prior to 15.1X53-D235; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R3; 17.3 versions prior to 17.3R3-S2, 17.3R4; 17.4 versions prior to 17.4R2-S1, 17.4R3; 18.1 versions prior to 18.1R3-S1, 18.1R4; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R2. Una cierta secuencia de paquetes BGP o IPv6 BFD válidos puede desencadenar un desbordamiento de búfer basado en pila en Junos OS Packet Forwarding Engine manager (FXPC), en dispositivos de las series QFX5000, EX4300, EX4600. Este problema puede resultar en un fallo del demonio fxpc o puede llevar a la ejecución remota del código. • http://www.securityfocus.com/bid/107897 https://kb.juniper.net/JSA10930 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
