CVE-2021-1353

TITLE

Cisco StarOS Security hole

Trust: 0.6

sources: CNNVD: CNNVD-202101-1526

DESCRIPTION

A vulnerability in the IPv4 protocol handling of Cisco StarOS could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a memory leak that occurs during packet processing. An attacker could exploit this vulnerability by sending a series of crafted IPv4 packets through an affected device. A successful exploit could allow the attacker to exhaust the available memory and cause an unexpected restart of the npusim process, leading to a DoS condition on the affected device. Cisco StarOS is a set of virtualization operating system of Cisco (Cisco)
