Name of the Vulnerable Software and Affected Versions libnids versions prior to 1.24

Description The issue allows remote attackers to cause a denial of service via crafted fragmented packets, resulting in a NULL pointer dereference and crash. This is due to a problem in the ip evictor function in ip fragment.c, which is used in products such as dsniff.
