Synopsis ========
Heartbeat is vulnerable to a Denial of Service which can be triggered by a remote attacker without authentication.
Background ==========
Heartbeat is a component of the High-Availability Linux project. It is used to perform death-of-node detection, communications and cluster management.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-cluster/heartbeat < 2.0.7 >= 2.0.7
Description ===========
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.
Resolution ==========
All Heartbeat users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-cluster/heartbeat-2.0.7"
