Linux kernel ESP packet denial of service
| linux-kernel-esp-dos (42276) |  Medium Risk |
Description:
Linux kernel is vulnerable to a denial of service, caused by an error in the IPsec implementation. By sending a specially-crafted fragmented ESP packet, a remote attacker could exploit this vulnerability to cause the router to crash.
*CVSS:
| Base Score: | 5 |
| Access Vector: | Network |
| Access Complexity: | Low |
