Description Mark J. Cox 2005-11-28 11:34:03 UTC 
This flaw affects 2.6 only, but affects RHEL4 due to the backport in ipsec.patch

+++ This bug was initially created as a clone of Bug #174345 +++

CVE-2005-3848 dst_entry leak
        Memory leak in the icmp_push_reply function in Linux 2.6
        before 2.6.12.6 and 2.6.13 allows remote attackers to cause a
        denial of service (memory consumption) via a large number of
        crafted packets that cause the ip_append_data function to
        fail, aka "DST leak in icmp_push_reply."

fixed upstream in 2.6.13.  Patch:
