Summary:
Updated LPRng packages fix psbanner vulnerability
Updated LPRng packages resolving a temporary file vulnerability are now
available.
Description:
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 a temporary file
with a known filename in an insecure manner. 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 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.
