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 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.
