Description

The remote host is affected by the vulnerability described in GLSA-200608-23 (Heartbeat: Denial of Service)

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).

Impact :

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

Workaround :

There is no known workaround at this time.
