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...

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...

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...

CVE-2019-0041

On EX4300-MP Series devices with any lo0 filters applied, transit network traffic may reach the control plane via loopback interface lo0. The device may fail to forward such traffic. This issue affects Juniper Networks Junos OS 18.2 versions prior to 18.2R1-S2, 18.2R2 on EX4300-MP Series. This...

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...

CVE-2019-0038

Crafted packets destined to the management interface fxp0 of an SRX340 or SRX345 services gateway may create a denial of service DoS condition due to buffer space exhaustion. This issue only affects the SRX340 and SRX345 services gateways. No other products or platforms are affected by this...

CVE-2019-0039

If REST API is enabled, the Junos OS login credentials are vulnerable to brute force attacks. The high default connection limit of the REST API may allow an attacker to brute-force passwords using advanced scripting techniques. Additionally, administrators who do not enforce a strong password...

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...

Design/Logic Flaw

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...

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...

CVE-2019-0040

On Junos OS, rpcbind should only be listening to port 111 on the internal routing instance IRI. External packets destined to port 111 should be dropped. Due to an information leak vulnerability, responses were being generated from the source address of the management interface e.g. fxp0 thus...

Stack overflow

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...

CVE-2019-0032 Junos Space Service Now and Service Insight: Organization username and password stored in plaintext in log files.

A password management issue exists where the Organization authentication username and password were stored in plaintext in log files. A locally authenticated attacker who is able to access these stored plaintext credentials can use them to login to the Organization. Affected products are: Juniper...

CVE-2019-0036

CVE-2019-0036 affects Juniper Networks Junos OS and causes stateless firewall filter terms named like internal-n (for example internal-1) to be silently ignored during configuration. The config commits without error, but the filter criteria can inadvertently match all packets, leading to unintend...

CVE-2019-0031 Junos OS: jdhcpd daemon memory consumption Denial of Service when receiving specific IPv6 DHCP packets.
