Base vector

AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: Cisco IOS XE Software (affected versions not specified)

Description: A vulnerability in the Protocol Independent Multicast (PIM) feature could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This issue is due to insufficient validation of received IPv4 PIMv2 packets. An attacker could exploit this by sending a crafted PIMv2 packet to a PIM-enabled interface on an affected device, potentially causing the device to reload and resulting in a DoS condition. The vulnerability can be exploited with either an IPv4 multicast or unicast packet.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
