Description

Receipt of a specially crafted Connectionless Network Protocol (CLNP) packet destined to an interface IP address 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 packet if ‘clns-routing’ or ESIS is explicitly configured. Devices without CLNS enabled are not vulnerable to this issue.

This issue only affects devices running Junos OS 15.1. Affected releases are Juniper Networks Junos OS:

  • 15.1 versions prior to 15.1F5-S3, 15.1F6-S8, 15.1F7, 15.1R5;

  • 15.1X53 versions prior to 15.1X53-D66, 15.1X53-D233, 15.1X53-D471.

Earlier releases are unaffected by this vulnerability, and the issue has been resolved in Junos OS 16.1R1 and all subsequent releases.
