CVE-2024-20464
A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XE Software...
A vulnerability in the Protocol Independent Multicast (PIM) feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to insufficient validation of received IPv4 PIMv2 packets. An attacker could exploit this vulnerability by sending a crafted PIMv2 packet to a PIM-enabled interface on an affected device. A successful exploit could allow the attacker to cause an affected device to reload, resulting in a DoS condition.
Note: This vulnerability can be exploited with either an IPv4 multicast or unicast packet.
