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

<p>
|
|
Eric Romang has discovered that Heartbeat insecurely creates
|
|
temporary files with predictable filenames.
|
|

|
|
<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.

|
|
<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 ">=sys-cluster/heartbeat-1.2.3-r1"</code>
