IPsec Tools isakmp_info_recv() denial of service
| ipsectools-isakmpinforecv-dos (33541) |  Low Risk |
Description:
IPsec Tools are vulnerable to a denial of service, caused by a vulnerability in the IPSec key exchange server. By sending specially-crafted packets using the isakmp_info_recv() function, a remote attacker could exploit this vulnerability to disrupt an existing IPSec tunnel, resulting in a denial of service.
