Vulnerability Name:

CCN-139097

Published:2018-01-24
Updated:2018-01-24
Summary:NetBSD is vulnerable to a denial of service, caused by the improper parsing of IPv6-AH packets by IPsec. By sending a specially crafted IPsec IPv6-AH packet with a sub-option of length zero, a remote attacker could exploit this vulnerability to cause the kernel to crash.
