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: > http://quickgit.kde.org/?p=kde-runtime.git&a=commit&h=14a8232d0b5b1bc5e0ad922292c6b5a1c501165c > > For KDE Frameworks 5 KWallet upgrade to 5.6.0 or apply the following patch: > http://quickgit.kde.org/?p=kwallet.git&a=commit&h=6e588d795e6631c3c9d84d85fd3884a159b45849 > > Credits > ======= > > Thanks to Itay Duvdevani for finding the issue and for letting us know. > Thanks to Valentin Rusu for implementing the fix.
