CVE-2018-0017

A vulnerability in the Network Address Translation - Protocol Translation NAT-PT feature of Junos OS on SRX series devices may allow a certain valid IPv6 packet to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition for the SRX device...

Design/Logic Flaw

On SRX Series devices during compilation of IDP policies, an attacker sending specially crafted packets may be able to bypass firewall rules, leading to information disclosure which an attacker may use to gain control of the target device or other internal devices, systems or services protected b...

CVE-2018-0021

If all 64 digits of the connectivity association name CKN key or all 32 digits of the connectivity association key CAK key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an...

CVE-2018-0016

Receipt of a specially crafted Connectionless Network Protocol CLNP datagram destined to an interface of a Junos OS device may result in a kernel crash or lead to remote code execution. Devices are only vulnerable to the specially crafted CLNP datagram if 'clns-routing' or ES-IS is explicitly...
