[GLSA-200508-05] Heartbeat: Insecure temporary file creation

Vulnerability Assessment Summary
Heartbeat: Insecure temporary file creation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200508-05
(Heartbeat: Insecure temporary file creation)

Eric Romang has discovered that Heartbeat insecurely creates
temporary files with predictable filenames.

Impact

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

There is no known workaround at this time.
