Secunia Research has discovered a vulnerability in the OpenOffice
implementation on Fedora Core 1 and Fedora Core 2, which potentially can
be exploited by malicious, local users to gain knowledge of sensitive
information.

Default installs create temporary OpenOffice documents with insecure
permissions ("664" or "644" depending on the user's umask) in the "/tmp"
folder.

Example:
/tmp/svelj.tmp/svemm.tmp

(The temporary folders and files are always named "sv???.tmp").

Successful exploitation allows an unprivileged user to read arbitrary
users' currently open documents.
