GLSA-200608-23 : Heartbeat: Denial of Service

medium Nessus Plugin ID 22285

Synopsis

The remote Gentoo host is missing one or more security-related patches.

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.

Solution

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