[GLSA-200608-23] Heartbeat: Denial of Service Vulnerability Scan
Vulnerability Scan Summary
Heartbeat: Denial of Service
Detailed Explanation for this Vulnerability Test
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.
