Package: guile-2.0
Version: 2.0.11+1-1
Tags: security
Guile automatically byte-compiles programs when they are run, and
places the byte-compiled file in a subdirectory of
$HOME/.cache/guile/.
However, the permissions of the byte-compiled file are derived from
umask rather than the permissions of the source file. This means that
sensitive data (e.g. a hard-coded password) contained in a source file
with restrictive permissions will be copied into a byte-compiled file
that may be world-readable.
Guile should ensure that the permissions of byte-compiled files match
those of the source.
Example:
$ touch myscript
$ chmod 700 myscript # source file readable only to owner
$ cat >> myscript <<'EOF'
#!/usr/bin/guile \
-e main -s
!#
(define secret-password "DEADBEEFDEADBEEF")
(define (main args)
(display "this program contains an embedded secret")
(newline))
EOF
$ ./myscript
;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;; or pass the --no-auto-compile argument to disable.
;;; compiling /home/rwp/./myscript
;;; compiled /home/rwp/.cache/guile/ccache/2.0-LE-4-2.0/home/rwp/myscript.go
this program contains an embedded secret
$ ls -l ~rwp/.cache/guile/ccache/2.0-LE-4-2.0/home/rwp/myscript.go
-rw-r--r-- 1 rwp rwp 456 Jul 1 12:00 /home/[...]/myscript.go
# ^^ Note that the byte-compiled file is world-readable
$ strings ~rwp/.cache/guile/ccache/2.0-LE-4-2.0/home/rwp/myscript.go
[...]
