[GLSA-200608-23] Heartbeat: Denial of Service |
||
|
Heartbeat: Denial of Service Detailed Explanation for this Vulnerability Assessment 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.
