Mandrake Linux Advisory: LPRng

Mandrake Linux Security Update Advisory

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.
