• CVE-2015-8359: DLL Preloading vulnerability on Windows
  The version of Qt bundled with KeePassX 0.4.3 is vulnerable to a DDL preloading attack.
  This vulnerability only affects KeePassX on Windows.
  If successfully exploited, arbitrary code can be executed in the context of KeePassX.
  KeePassX 0.4.4 ships with Qt 4.8.7 and employs additional hardening measures.
  Thanks to Trenton Ivey from SecureWorks for reporting this vulnerability to us.
• CVE-2015-8378: Canceling XML export function creates export as “.xml” file
  When canceling the “Export to > KeePassX XML file” function the cleartext passwords were still exported.
  In this case the password database was exported as the file “.xml” in the current working directory (often $HOME or the directory of the database).
  Originally reported as Debian bug #791858

KeePassX 0.4.4 fixes both vulnerabilities.
It is available as a source tarball and Windows / Mac OS X binaries: Download
The OS X bundle contains only a 64bit binary (compared to 0.4.3 which shipped as i386 and powerpc).
The fix for CVE-2015-8378 is also available as a patch: CVE-2015-8378.patch

We will still provide security support for the 0.4 series for some time but please consider updating to version 2.0 instead.

KeePassX 2.0 is using the new .kdbx (same as KeePass 2) database format.
You can import your .kdb database from 0.4 from the Database > Import KeePass 1 database.
This is a one-way process though. You can’t migrate back to the .kdb format.

New features include:

• Multiple attachments per entry
• Add custom key/value pairs to entries
• Open multiple database in one window

KeePassX 2.0 has been rewritten from scratch so some features (like showing expired passwords) are still missing.

The important changes compared to beta 2 are:

• Improve UI of the search edit.
• Clear clipboard when locking databases. [#342]
• Enable Ctrl+M shortcut to minimize the window on all platforms. [#329]
• Show a better message when trying to open an old database format. [#338]
• Fix global auto-type behavior with some window managers.
• Show global auto-type window on the active desktop. [#359]
• Disable systray on OS X. [#326]
• Restore main window when clicking on the OS X docker icon. [#326]

You can fetch the new release from the downloads page.

The most important changes are:

• Fix crash when locking with search UI open [#309]
• Fix file locking on Mac OS X [#327]
• Set default extension when saving a database [#79, #308]

Beware: this is a beta release. While I believe the code base is already rather stable make sure to regularly backup your database.

The most important changes are:

• Remember entry column sizes [#159]
• Add translations
• Support opening attachments directly
• Support cmd:// URLs [#244]

• Make the kdbx parser more lenient
• Remove –password command line option [#285]
• Lots of bugfixes

Special thanks to all the contributers who reported bugs, translated KeePassX and submitted pull requests.

I hope to keep this release cycle much shorter than the previous ones. Only bugfixes and translation updates
will make it into 2.0 at this point.

The development of version 2.1 will start in the master branch while 2.0 will be maintained in it’s own branch.
As Qt 4 will be EOL soon KeePassX 2.1 will only support Qt 5.

Beware: this is a beta release. While I believe the code base is already rather stable make sure to regularly backup your database.

That said I hope to be able to release the first beta in the not too distant future.
The main blockers are two features: CSV export and file locking (so you can’t accidentally overwrite a database that has been opened by another user).
After the beta release we will focus on bugfixes in preparation for the final version 2.0.

That’s it for now. I’ll try to post updates about the development progress more regularly from now on.
Thanks for sticking with us!
