Description p.jenner 2000-10-10 08:36:32 UTC 
There is a /tmp symlink vulnerability in gnorpm 0.9 shipped in Red Hat
6.2.  From bugtraq id 1761:

<quote>
A vulnerabiity exists in versions prior to v0.95 of GnoRPM, the Gnome
graphical RPM manager, involving the way gnomerpm handles tmp files.
GnomeRPM creates temporary files in the world-writeable /tmp directory with
preditable filenames. It is possible for a malicious user to create
symbolic links in /tmp with guessed/predicted filenames, knowing in advance
that GnomeRPM will be run by root. When this happens, the files pointed to
by the correctly guessed symbolic links will be overwritten by GnomeRPM (as
root).
<unquote>

This vulnerability is fixed in gnorpm 0.95.1 and Red Hat should upgrade to
this version to fix the vulnerability.

I hope this helps,

Paul
