ml85p is a Linux driver for Samsung ML-85G series printers. It may be bundled with distributions of Ghostscript.
  
ml85p does not check for symbolic links when creating image output files.
  
These files are created in /tmp with a guessable naming format, making it trivial for attackers to exploit this vulnerability.
  
Since user-supplied data is written to the target file, attackers may be able to elevate privileges.
