CVE-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 •
CVE-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 •
CVE-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 •

https://notcve.org/view.php?id=CVE-2019-0005
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. En las series EX2300, EX3400, EX4600, QFX3K y QFX5K, la configuración del filtro del firewall no puede realizar la concordancia de paquetes en ninguna cabecera de extensión IPv6. • http://www.securityfocus.com/bid/106665 https://kb.juniper.net/JSA10905 • CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-0014 – Junos OS: QFX and PTX Series: FPC process crashes after J-Flow processes a malformed packet
https://notcve.org/view.php?id=CVE-2019-0014
On QFX and PTX Series, receipt of a malformed packet for J-Flow sampling might crash the FPC (Flexible PIC Concentrator) process which causes all interfaces to go down. By continuously sending the offending packet, an attacker can repeatedly crash the FPC process causing a sustained Denial of Service (DoS). This issue affects both IPv4 and IPv6 packet processing. Affected releases are Juniper Networks Junos OS on QFX and PTX Series: 17.4 versions prior to 17.4R2-S1, 17.4R3; 18.1 versions prior to 18.1R3-S1; 18.2 versions prior to 18.2R1-S3, 18.2R2; 17.2X75 versions prior to 17.2X75-D91, 17.2X75-D100. En las series QFX y PTX, la recepción de un paquete mal formado para el muestreo de J-Flow podría provocar el cierre inesperado del proceso FPC (Flexible PIC Concentrator), que provoca que todas las interfaces se caigan. • http://www.securityfocus.com/bid/106556 https://kb.juniper.net/JSA10914 • CWE-19: Data Processing Errors •
