RHEL 2.1 : LPRng (RHSA-2003:150)
Low Nessus Plugin ID 12391
SynopsisThe remote Red Hat host is missing a security update.
DescriptionUpdated 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.
SolutionUpdate the affected LPRng package.
