a) Use it as a course example on why not to write programs in sh
b) Throw it out and write it in C
For the moment however this one appears to be covered ok by using
uudecode's -o option to force the output file.
A couple of scripts in metamail (notably sun-audio-file) blindly uudecode
something assuming the filename will be reasonable. It does do things
in a /tmp dir but if you know someones home dir and bung in a full path
then suprise suprise it uudecodes where asked - so you can send people
sun-audio-file .rhosts for example.
It seems to be sufficient to change from
if (! $?METAMAIL_TMPDIR) then
set METAMAIL_TMPDIR=/tmp
endif
cd ${METAMAIL_TMPDIR}
uudecode < $1
audiotool audio-file
To use
uudecode <$1 -o audio-file
This isnt the only problem file tho.
This seems affect anybody using metamail - thats generally folks using Elm
and things like Andrew in some cases. Several Linux distributions ship
a metamail kit. A fix for Redhat 4.x is now available on ftp.redhat.com.
