Subject: CVE Request: kwallet: incorrect CBC encryption handling


The following KDE Project Security Advisory was issued at .

> Title:          Fix kwalletd CBC encryption handling
> Risk Rating:    Low
> Platforms:      All
> Versions:       kwalletd < Applications 14.12.1, KF5::KWallet < 5.6.0
> Author:         Valentin Rusu <>
> Date:           9 January 2015
> Overview
> ========
> Until KDE Applications 14.12.0, kwalletd incorrectly handled CBC encryption blocks when
> encrypting secrets in kwl files. The secrets were still encrypted, but the
> result binary data corresponded to an ECB encrypted block instead of CBC.
> Impact
> ======
> The ECB encryption algorithm, even if it'll scramble user data, it'll produce
> same encrypted byte sequence for the same input text. As a result, attackers
> may eventually find-out the encrypted text.
> Solution
> ========
> For kde-runtime KWallet upgrade to KDE Applications 14.12.1 or apply the following patch:
> For KDE Frameworks 5 KWallet upgrade to 5.6.0 or apply the following patch:
> Credits
> =======
> Thanks to Itay Duvdevani for finding the issue and for letting us know.
> Thanks to Valentin Rusu for implementing the fix.
