Description Mark J. Cox 2004-12-12 10:47:33 UTC 
isec.pl reported to vendor-sec some flaws in igmp handling which could allow a
local user to cause a kernel deadlock or crash.  They also say it's likely that
you could gain privileges using this flaw.  Looks like only 2.4.22 and above are
affected.

Embargo until 20041214
