CVE-2019-0037 – Junos OS: jdhcpd crash upon receipt of crafted DHCPv6 solicit message

https://notcve.org/view.php?id=CVE-2019-0037

In a Dynamic Host Configuration Protocol version 6 (DHCPv6) environment, the jdhcpd daemon may crash and restart upon receipt of certain DHCPv6 solicit messages received from a DHCPv6 client. By continuously sending the same crafted packet, an attacker can repeatedly crash the jdhcpd process causing a sustained Denial of Service (DoS) to both IPv4 and IPv6 clients. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D171, 15.1X49-D180; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496; 16.1 versions prior to 16.1R3-S10, 16.1R7-S4; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S2; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D30; 18.3 versions prior to 18.3R1-S2. This issue does not affect Junos OS releases prior to 15.1. En un entorno de Protocolo de configuración dinámica de host versión 6 (DHCPv6), el demonio jdhcpd puede bloquearse y reiniciarse al recibir ciertos mensajes de solicitud de DHCPv6 de un cliente DHCPv6. • http://www.securityfocus.com/bid/107894 https://kb.juniper.net/JSA10926 •

CVE-2019-0036 – Junos OS: Firewall filter terms named "internal-1" and "internal-2" being ignored

https://notcve.org/view.php?id=CVE-2019-0036

When configuring a stateless firewall filter in Junos OS, terms named using the format "internal-n" (e.g. "internal-1", "internal-2", etc.) are silently ignored. No warning is issued during configuration, and the config is committed without error, but the filter criteria will match all packets leading to unexpected results. Affected releases are Juniper Networks Junos OS: All versions prior to and including 12.3; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D161, 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D69; 16.1 versions prior to 16.1R7-S4, 16.1R7-S5; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S7, 17.4R2-S3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S4; 18.2 versions prior to 18.2R1-S5, 18.2R2-S1; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3; 18.4 versions prior to 18.4R1-S1, 18.4R1-S2. Cuando se configura un filtro de cortafuegos sin estado en Junos OS, los términos nombrados con el formato "internal-n" (por ejemplo, "internal-1", "internal-2", etc.) se ignoran en silencio. • https://kb.juniper.net/JSA10925 • CWE-284: Improper Access Control CWE-754: Improper Check for Unusual or Exceptional Conditions •

CVE-2019-0035 – Junos OS: 'set system ports console insecure' allows root password recovery on OAM volumes

https://notcve.org/view.php?id=CVE-2019-0035

When "set system ports console insecure" is enabled, root login is disallowed for Junos OS as expected. However, the root password can be changed using "set system root-authentication plain-text-password" on systems booted from an OAM (Operations, Administration, and Maintenance) volume, leading to a possible administrative bypass with physical access to the console. OAM volumes (e.g. flash drives) are typically instantiated as /dev/gpt/oam, or /oam for short. Password recovery, changing the root password from a console, should not have been allowed from an insecure console. Affected releases are Juniper Networks Junos OS: 15.1 versions prior to 15.1F6-S12, 15.1R7-S3; 15.1X49 versions prior to 15.1X49-D160; 15.1X53 versions prior to 15.1X53-D236, 15.1X53-D496, 15.1X53-D68; 16.1 versions prior to 16.1R3-S10, 16.1R6-S6, 16.1R7-S3; 16.1X65 versions prior to 16.1X65-D49; 16.2 versions prior to 16.2R2-S8; 17.1 versions prior to 17.1R2-S10, 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R3-S1; 17.3 versions prior to 17.3R3-S3; 17.4 versions prior to 17.4R1-S6, 17.4R2-S2; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R2; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S2. • https://kb.juniper.net/JSA10924 • CWE-501: Trust Boundary Violation CWE-522: Insufficiently Protected Credentials •

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 •
