Detailed vulnerability description
The vulnerability allow a remote attacker to cause DoS condition or potentially execute arbitrary code on the target syste.
The weakness exists due to buffer overflow in print-ether.c:ether_print() in multiple protocol parsers (Geneve, GRE, NSH, OTV, VXLAN and VXLAN GPE). A remote attacker can use a specially crafted protocol to trigger memory corruption and cause the application to crash or possibly execute arbitrary code.
Successful exploitation of the vulnerability may result system compromise.
