Description
The issue is related to errors in processing Connectionless Network Protocol (CLNP) packets in the Junos OS. Receipt of a specially crafted CLNP datagram may result in a kernel crash or lead to remote code execution. Devices are only vulnerable if 'clns-routing' or ES-IS is explicitly configured. Devices without CLNS enabled or with IS-IS configured on the interface are not vulnerable unless CLNS routing is also enabled.
Recommendations
For Junos OS versions prior to 15.1F5-S3, update to 15.1F5-S3 or later.
For Junos OS versions prior to 15.1F6-S8, update to 15.1F6-S8 or later.
For Junos OS versions prior to 15.1F7, update to 15.1F7 or later.
For Junos OS versions prior to 15.1R5, update to 15.1R5 or later.
For Junos OS 15.1X49 versions prior to 15.1X49-D60, update to 15.1X49-D60 or later.
For Junos OS 15.1X53 versions prior to 15.1X53-D66, update to 15.1X53-D66 or later.
For Junos OS 15.1X53 versions prior to 15.1X53-D233, update to 15.1X53-D233 or later.
For Junos OS 15.1X53 versions prior to 15.1X53-D471, update to 15.1X53-D471 or later.
As a temporary workaround, consider disabling 'clns-routing' or ES-IS until a patch is available. Restrict access to interfaces with CLNS enabled to minimize the risk of exploitation.
