<title>ipsec-tools and iputils contain a remote DoS vulnerability</title>
|
|
<synopsis>
|
|
racoon, which is included in the ipsec-tools and iputils packages in
|
|
Portage, does not check the length of ISAKMP headers. Attackers may be able
|
|
to craft an ISAKMP header of sufficient length to consume all available
|
|
system resoources, causing a Denial of Service.

|
|
When racoon receives an ISAKMP header, it allocates memory based on the
|
|
length of the header field. Thus, an attacker may be able to cause a Denial
|
|
of Services by creating a header that is large enough to consume all
|
|
available system resources.
