RHEL 2.1 : LPRng (RHSA-2003:150)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated LPRng packages resolving a temporary file vulnerability are
now available.

LPRng is a print spooler. LPRng includes a program, psbanner, that can
be used to produce Postscript banner pages to separate print jobs.

A vulnerability has been found in psbanner, which creates in an
insecure manner a temporary file with a known filename. An attacker
could create a symbolic link and cause arbitrary files to be written
as the lp user.

Note: psbanner is not used by the default Red Hat Enterprise Linux
LPRng configuration.

Users that have configured LPRng to use psbanner should install these
updated packages, which contain a patch so that psbanner does not
create the temporary file.
