The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200408-08
(Cfengine: RSA Authentication Heap Corruption)
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
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.
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.)
