CVE-2003-0136 |
Details
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.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
