Description Steven Bakker 2008-09-29 13:57:13 UTC
Description of problem:

When trying to open a gpg encrypted file with gjots2, the program asks for a passphrase and subsequently uses the (unescaped) answer in a popen() command line:

   f = os.popen("echo " + self.gui.password + " | gpg ...");

(lines 310 and 313 of lib/file.py)

This can cause errors from the shell if the actual pass-phrase contains shell meta-characters and can lead to unintentional side-effects.

Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1. Use gjots2 to open a gpg encrypted file.
2. In the password dialog, enter: ;touch /tmp/U-R-HACKED;echo

Actual results:

There is now a file U-R-HACKED in /tmp.

Expected results:

No side effects.

Additional info:

This is in lib/file.py in the source distribution around lines 310 and 313. I don't know enough Python to suggest a good fix for this.

It's probably not so much a security issue as a possibly nasty bug. If my password contains a single quote, or a "$", or any other shell meta-character, I will not be able to decrypt my file.

No idea if this has been fixed in 2.3.7 (which is the latest version).
