                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           LPRng
Advisory ID:            MDKSA-2003:060
Date:                   May 21st, 2003

Affected versions:      8.2, 9.0, Corporate Server 2.1
________________________________________________________________________

Problem Description:

 Karol Lewandowski discovered a problem with psbanner, a printer filter
 that creates a PostScript format banner.  psbanner creates a temporary
 file for debugging purposes when it is configured as a filter, and does
 not check whether or not this file already exists or is a symlink.  The
 filter will overwrite this file, or the file it is pointing to (if it
 is a symlink) with its current environment and called arguments with the
 user id that LPRng is running as.
