Synopsis
========

Kwalletd password stores are vulnerable to codebook attacks.

Background
==========

Kwalletd is is a credentials management application for KDE.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 kde-apps/kwalletd < 4.14.3-r2 >= 4.14.3-r2

codebook attack in order to obtain confidential passwords.

Workaround
==========

There is no known workaround at this time.

Resolution

All kwalletd users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=kde-apps/kwalletd-4.14.3-r1"
