Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version number, the remote Juniper Junos device is affected by a denial of service vulnerability due to improper handling of BGP UPDATE messages using 4-byte AS numbers. A remote attacker can exploit this issue, by sending a specially crafted BGP UPDATE packet, to crash the 'rpd' process.

Note that this issue only affects devices with the BGP daemon enabled and support for 4-byte AS numbers.

Solution

Apply the relevant Junos software release or workaround referenced in Juniper advisory JSA10653.
