I also see no -P- and no absolute paths for the ps files mentioned in
many "gs scripts" e.g. /usr/bin/pdf2dsc or /usr/bin/ps2ascii . Also,
crappy coding for "GS_EXECUTABLE=gs". Am not sure if these are
"originally gs" or "Debian special".

I believe they're all part of the standard Ghostscript distribution; at
any rate, they're in the Windows Ghostscript distribution I have
installed here.

The Windows scripts (gs*\lib\*.bat) are similarly vulnerable: no use of
-P-, and letting the executable name be overridden by an environment
