+ <title>Cfengine: RSA Authentication Heap Corruption</title>
+ <synopsis>
+ Cfengine is vulnerable to a remote root exploit from clients in
+ AllowConnectionsFrom.

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

+ <description>
+ <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>
+ </description>
+ <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:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv "&gt;=net-misc/cfengine-2.1.8"
+ # emerge "&gt;=net-misc/cfengine-2.1.8"</code>
