Description Mark J. Cox 2005-11-28 10:54:38 UTC

Although this issue does not affect 2.4 kernels, RHEL4 added this flaw in
*ipsec.patch

+++ This bug was initially created as a clone of Bug #174343 +++

Memory leak in the ip6_input_finish function in ip6_input.c in
        Linux kernel 2.6.12 and earlier might allow attackers to cause
        a denial of service via malformed IPv6 packets with
        unspecified parameter problems, which prevents the SKB from
        being freed.
