TITLE:
KAME Racoon IKE Generic Payload Header Denial of Service
SECUNIA ADVISORY ID:
SA11411
VERIFY ADVISORY:
http://secunia.com/advisories/11411/
CRITICAL:
Moderately critical
IMPACT:
DoS
WHERE:
From remote
SOFTWARE:
KAME Racoon
DESCRIPTION:
John Lampe has reported a vulnerability in Racoon, which can be
exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error when processing certain
malformed IKE messages. This can be exploited via a specially crafted
IKE message with a malformed Generic Payload Header containing
invalid values in the "Security Association Next Payload" field and a
reserved field.
Successful exploitation causes the application to enter an infinite
loop, which consumes large amounts of system resources and drops
connections.
The vulnerability affects versions prior than 20040407b.
SOLUTION:
Update to version 20040407b or later.
PROVIDED AND/OR DISCOVERED BY:
