Cfengine is an agent/software robot and a high level policy language
|
|
for building expert systems to administrate and configure large
|
|
computer networks.

<p>
|
|
Two vulnerabilities have been found in cfservd. One is a buffer
|
|
overflow in the AuthenticationDialogue function and the other is a
|
|
failure to check the proper return value of the ReceiveTransaction
|
|
function.
|
|
</p>
|
|

|
|
<impact type="high">
|
|
<p>
|
|
An attacker could use the buffer overflow to execute arbitrary code
|
|
with the permissions of the user running cfservd, which is usually the
|
|
root user. However, before such an attack could be mounted, the
|
|
IP-based ACL would have to be bypassed. With the second vulnerability,
|
|
an attacker could cause a denial of service attack.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are encouraged to
|
|
upgrade to the latest available version of Cfengine. (It should be
|
|
noted that disabling cfservd will work around this particular problem.
|
|
However, in many cases, doing so will cripple your Cfengine setup.
|
|
Upgrading is strongly recommended.)
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Cfengine users should upgrade to the latest version:
