             DATE : 2003-07-11 13:57 UTC
          EXPLOIT : remote

quote from CVE:
"Cistron RADIUS daemon (radiusd-cistron) 1.6.6 and earlier allows remote 
attackers to cause a denial of service and possibly execute arbitrary 
code via a large value in an NAS-Port attribute, which is interpreted 
as a negative number and causes a buffer overflow."

SOLUTION

It is recommended that all Gentoo Linux users who are running
net-dialup/cistronradius upgrade to cistronradius-1.6.6-r1 as follows

emerge sync
emerge cistronradius
emerge clean
