It includes encryption, regexp searches, and a date-sorted list for editing old entries. Since Bournal is pure bash, it should be easily editable for the CLI-savvy.". Product Link: http://becauseinter.net/bournal/ ====================================================================== 4) Description of Security Issue 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. ====================================================================== 5) 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. ====================================================================== 6) Time Table 12/02/2010 - Vendor notified. 12/02/2010 - Vendor response. 22/02/2010 - Public disclosure. ====================================================================== 7) Credits Discovered by Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has assigned CVE-2010-0119 for the security issue. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: http://secunia.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security. http://secunia.com/advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: http://secunia.com/secunia_research/ Secunia regularly hires new skilled team members.
