Synopsis :

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

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

Risk factor :

Medium / CVSS Base Score : 5.0
