Description


Secunia Research has discovered a security issue in Bournal, which can be exploited by malicious, local users to disclose sensitive information.

The script uses e.g. the insecure "-K" command line parameter to pass the key to the ccrypt utilities, which can be exploited to obtain the key from the list of running processes.

Note: This may not affect recent Linux versions, but is confirmed for FreeBSD 8.0. Other systems may also be affected.


Solution:
Fixed in version 1.4.1 by preventing the use of the script on FreeBSD systems. This may still affect other systems where users have access to the full command line of other user's processes, despite ccrypt disabling "echoing" on the terminal.
