Vulnerability identifier: #VU59595
Vulnerability risk: Medium
Exploitation vector: Network
Exploit availability: No
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to resource exhaustion in the NETISR network queue functionality. A remote attacker can send specially crafted packets over an IPv4 unicast routing equal-cost multi-path (ECMP) unilist selection and force the routing protocol daemon (rpd) to consume all available CPU resources.
Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition.
