GLSA-200608-23 : Heartbeat: Denial of Service

Medium Nessus Plugin ID 22285


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


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.


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