The remote host is missing an update to heartbeat announced via advisory DSA 761-1. Eric Romang discovered several insecure temporary file creations in heartbeat, the subsystem for High-Availability Linux. For the old stable distribution (woody) these problems have been fixed in version 0.4.9.0l-7.3.

For the stable distribution (sarge) these problems have been fixed in version 1.2.3-9sarge2. For the unstable distribution (sid) these problems have been fixed in version 1.2.3-12. We recommend that you upgrade your heartbeat package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20761-1
