Yan Rong Ge discovered that the peel_netstring() function in
|
|
cl_netstring.c does not validate the "length" parameter of user input,
|
|
which can lead to an out-of-bounds memory access when processing
|
|
certain Heartbeat messages (CVE-2006-3121). Furthermore an unspecified
|
|
local DoS issue was fixed (CVE-2006-3815).

|
|
By sending a malicious UDP Heartbeat message, even before
|
|
authentication, a remote attacker can crash the master control process
|
|
of the cluster.
|
|
</p>

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

All Heartbeat users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose sys-cluster/heartbeat</code>
