Juniper Junos 12.1x47 UDP Denial Of Service Vulnerability
28 Nov. 2016
Juniper Junos OS before 12.1X46-D45, 12.1X46-D50, 12.1X47 before 12.1X47-D35, 12.3X48 before 12.3X48-D30, 13.3 before 13.3R9-S1, 14.1 before 14.1R7, 14.2 before 14.2R6, 15.1 before 15.1F2-S5, 15.1F4 before 15.1F4-S2, 15.1R before 15.1R2-S3, 15.1 before 15.1R3, and 15.1X49 before 15.1X49-D40 allow remote attackers to cause a denial of service (kernel crash) via a crafted UDP packet destined to the interface IP address of a 64-bit OS device. .
Receipt of a specifically crafted UDP packet destined to an interface IP address of a Junos OS device with a 64-bit platform may result in a kernel crash. This issue only affects systems running 64-bit Junos OS on a 64-bit routing engine (RE). 32-bit systems are unaffected by this vulnerability.
