CVE-2019-0039

CVE-2019-0039 affects Junos OS where REST API is enabled, enabling brute-force login attempts due to a high default connection limit. Publicly documented details list affected Junos OS versions (e.g., 14.1X53 before 14.1X53-D49; 15.1 family before various 15.x builds; up to 18.3R1-S1), with remed...

CVE-2019-0028 Junos OS: RPD process crashes due to specific BGP peer restarts condition.

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-2019-0041 Junos OS: EX4300-MP Series: IP transit traffic can reach the control plane via loopback interface.

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-2019-0036

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.
