Description Stefan Behte (RETIRED) gentoo-dev Security 2009-03-12 20:56:17 UTC 
CVE-2009-0778 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-0778):
  The icmp_send function in net/ipv4/icmp.c in the Linux kernel before
  2.6.25, when configured as a router with a REJECT route, does not
  properly manage the Protocol Independent Destination Cache (aka DST)
  in some situations involving transmission of an ICMP Host Unreachable
  message, which allows remote attackers to cause a denial of service
  (connectivity outage) by sending a large series of packets to many
  destination IP addresses within this REJECT route, related to an
  "rt_cache leak."

hardened-kernel unaffected at present time. Removing alias.
