An attacker can exploit this vulnerability to cause memory leak.
The vulnerability classification has been performed by using the CVSSv3 scoring system (http://www.first.org/cvss/specification-document).
Base Score: 4.3 (AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
Temporal Score: 4.0 (E:F/RL:O/RC:C)
This vulnerability can be exploited only when the following conditions are present:
1. An attacker could access to the LAN side of the device.
2. The MPLS function of the device is enable and LDP packets can be received and handled in the access site.
Vulnerability details:
An unauthenticated attacker may send specific Label Distribution Protocol (LDP) packets to the devices. When the values of some parameters in the packet are abnormal, the LDP processing module does not release the memory to handle the packet, resulting in memory leak.
