Description
An improper input validation weakness in the device control daemon process (dcd) of Juniper Networks Junos OS allows an attacker to cause a Denial of Service to the dcd process and interfaces and connected clients when the Junos device is requesting an IP address for itself. Junos devices are not vulnerable to this issue when not configured to use DHCP. Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D40 on SRX Series; 12.3X48 versions prior to 12.3X48-D20 on SRX Series; 14.1X53 versions prior to 14.1X53-D40 on EX2200/VC, EX3200, EX3300/VC, EX4200, EX4300, EX4550/VC, EX4600, EX6200, EX8200/VC (XRE), QFX3500, QFX3600, QFX5100; 15.1X49 versions prior to 15.1X49-D20 on SRX Series; 15.1X53 versions prior to 15.1X53-D68 on QFX10000 Series; 15.1X53 versions prior to 15.1X53-D235 on QFX5200/QFX5110; 15.1X53 versions prior to 15.1X53-D495 on NFX150, NFX250; 15.1X53 versions prior to 15.1X53-D590 on EX2300/EX3400; 15.1 versions prior to 15.1R7-S2.
