Red Hat Product Errata RHSA-2003:150 normal SHIPPED_LIVE Low: LPRng security update 2003-05-22 00:00:00 EDT

  None (edit)
Description Mark J. Cox 2003-04-14 07:35:08 EDT
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.

This is RHSA-2003:142, CAN-2003-0136
