+  <title>Heartbeat: Insecure temporary file creation</title>
+  <synopsis>
+    Heartbeat is vulnerable to symlink attacks, potentially allowing a local
+    user to overwrite arbitrary files.

+    <package name="sys-cluster/heartbeat" auto="yes" arch="*">

+  <background>
+    <p>
+    Heartbeat is a component of the High-Availability Linux project.
+    It it used to perform death-of-node detection, communications and
+    cluster management.

+  <description>
+    <p>
+    Eric Romang has discovered that Heartbeat insecurely creates
+    temporary files with predictable filenames.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the temporary file
+    directory, pointing to a valid file somewhere on the filesystem. When a
+    vulnerable script is executed, this could lead to the file being
+    overwritten with the rights of the user running the affected
+    application.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Heartbeat users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=sys-cluster/heartbeat-1.2.3-r1&quot;</code>
