(Netpbm: Multiple temporary file issues)

    Utilities contained in the Netpbm package prior to the 9.25 version contain
    defects in temporary file handling. They create temporary files with
    predictable names without checking first that the target file doesn't
    already exist.
  
Impact :

    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When a
    user or a tool calls one of the affected utilities, this would result in
    file overwriting with the rights of the user running the utility.
  
Workaround :

    There is no known workaround at this time."
