CVE-2021-1353 (GCVE-0-2021-1353)

Vulnerability from cvelistv5 – Published: 2021-01-20 20:00 – Updated: 2024-11-12 20:21
VLAI?
Summary
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.
Severity ?
