CVE-1999-1018 (CCN-6516)

Assigned:1999-07-27
Published:1999-07-27
Updated:2016-10-18
Summary:IPChains in Linux kernels 2.2.10 and earlier does not reassemble IP fragments before checking the header information, which allows a remote attacker to bypass the filtering rules using several fragments with 0 offsets.
