STRIP 2.2.1 for Android and OS X released

This morning we're excited to pull the switch on two important updates to STRIP for Android and OS X. STRIP for Android is carrying numerous bug fixes we've been working on for a while and a new full-screen theme. STRIP for OS X has been updated to fix the previously noted data persistence bug and is now quite a bit more robust in that department.

Bug in STRIP for OS X 2.2.0

We've tracked down an ugly little bug in the latest update of STRIP for OS X, 2.2.0, involving data persistence for newly added or edited fields on entry records. While the bug itself has one main root due to a recent change in STRIP's plumbing, it can be demonstrated in a couple of ways outlined below. These bugs can be worked around and we have a bugfix release 2.2.1 in the App Store review pipeline now. With any luck we'll have the update in the Mac App Store next week.

Avoiding Data Loss

To edit a record in STRIP the customers clicks on the Edit button (or command+E) to begin editing. Edits to field values are not being saved immediately, but are being delayed until the user again clicks on Edit. Therein lies a good deal of the problem. If the customer chooses to then launch Sync before ending editing, or uses the "Create new label" feature the field values get whacked and are lost.

To avoid any data loss with STRIP 2.2.0 for OS X avoid using the Create new label feature until we get 2.2.1 out, and remember to end editing by clicking on the Edit button to ensure your chanages are saved. You can add new labels in the interim by going to the File menu and selecting Customize Labels.

STRIP 2.2.1 ensures edits are persisted to the encrypted database immediately as before. We apologize for the oversight, it's an embarassing bug.

Heartbleed Security Statement for Tempo

We've been working hard at Zetetic to assess the impact for our Tempo Time Tracking customers resulting from the recent OpenSSL security disclosure known as the OpenSSL Heartbleed bug.

This issue has undermined the security of many internet platforms by allowing attackers to read arbitrary memory from services using the popular OpenSSL library to provide secure communications over the web. This attack can allow extraction of private keys, session data, and user information from affected websites.

Web Security for Tempo

Zetetic's public Tempo web services do use OpenSSL, but are not secured by a version that is vulnerable to the Heartbleed attack. In addition Tempo utilizes Amazon Web Services, widely reported to be susceptible to the Heartbleed attack, but does not terminate SSL on the Elastic Load Balancers that were discovered to be vulnerable.

As a result, users who currently rely on Tempo for time tracking should not need to be concerned with Heartbleed exposure through the Tempo web sites.

Even though the Tempo services should not be directly affected, out of an abundance of caution, we have still taken the step of revoking and reissuing new SSL Certificates for all Zetetic web applications.

Recommendations

This is a good time to review the strength of your application passwords. You should change your Tempo password immediately if you:

  1. Are currently sharing the same password for Tempo as any other application

  2. Are currently using a weak password for Tempo that doesn't meet the recommendations below

We recommend using a strong alphanumeric password with a combination of upper case, lowercase, digits, and meta-characters of the maximum length possible to allow for convenient entry.

We take security seriously and we are happy to communicate with customers about the details of this issue, or how to take appropriate action, so please don't hesitate to contact us if you have any questions.

Heartbleed Security Statement for STRIP Password Manager

Like most service and software providers, we've been working hard at Zetetic to assess the impact for our customers resulting from this week's OpenSSL security disclosure, commonly known as the OpenSSL Heartbleed bug. More specifically referred to as CVE-2014-0160, this issue has undermined the security of many internet platforms by allowing attackers to read arbitrary memory from services using the popular OpenSSL library to provide secure communications over the web. This attack can allow extraction of private keys, session data, and user information from affected websites.

STRIP, SQLCipher, and OpenSSL

Users of the STRIP Password Manager may recall that the application uses Zetetic's SQLCipher encrypted database library to protect all underlying application data. While SQLCipher does make use of OpenSSL, it only relies on low-level encryption interfaces. Since there is no use of OpenSSL's SSL functions, there is nothing that would expose SQLCipher or STRIP to direct attack via Heartbleed. More details on the use of OpenSSL in SQLCipher are available separately in our Heartbleed Security Statement for SQLCipher.

As a result, we're pleased to report that users who currently rely on STRIP for their data security need not be concerned with Heartbleed exposure on their local computers and devices a result of the software.

STRIP Cloud Sync

It's important to note that STRIP does provide a variety of optional synchronization features that use cloud services like Dropbox and Google Drive. Both of those services used affected versions of OpenSSL in the past, and may have been vulnerable to the Heartbleed bug.

STRIP's synchronization features do keep copies of the encrypted STRIP data on the cloud service. However, STRIP is very careful never to expose any unencrypted data to cloud services during synchronization. All STRIP data stored in Dropbox or Google Drive is fully encrypted using a strong encryption key derived from your master password.

While there haven't been any public reports of attackers using Heartbleed against Google or Dropbox, the nature of the bug make it possible that data on those services could have accessed without knowledge. However, since the database is fully encrypted at rest using STRIP, there is no risk of plaintext data exposure.

Recommendations

Even with STRIP's advanced protections, this is a really good time to review the strength of your master password, because STRIP's security really comes down to the security of your passphrase.

We recommend using an alphanumeric passphrase with a combination of upper case, lowercase, digits, and meta-characters of the maximum length possible to allow for convenient entry.

If you are currently using a weak password, especially in combination with Cloud sync, we'd strongly recommend that you change your STRIP password now to ensure the long term security of your data.

Finally, many internet sites have been affected by the Heartbleed bug, and are issuing statements suggesting that users change their passwords, log out of mobile applications, and reset authentication tokens, etc. Please take these notices seriously and update your credentials for affected systems as soon as possible.

We take security seriously and we are happy to communicate with customers about the details of this issue, or how to take appropriate action, so please don't hesitate to contact us if you have any questions.
