CESA-2003:150: LPRng 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 CentOS 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.
