Arch Linux Security Advisory ASA-201706-17
==========================================

Severity: Medium
Date    : 2017-06-14
CVE-ID  : CVE-2017-9604
Package : messagelib
Type    : information disclosure
Remote  : Yes
Link    : https://security.archlinux.org/AVG-300

Summary
=======

The package messagelib before version 17.04.2-1 is vulnerable to
information disclosure.

Resolution
==========

Upgrade to 17.04.2-1.

# pacman -Syu "messagelib>=17.04.2-1"

The problem has been fixed upstream in version 17.04.2.

Workaround
==========

None.

Description
===========

KDE kmail before 5.5.2 and messagelib before 5.5.2, as distributed in
KDE Applications before 17.04.2, do not ensure that a plugin's
sign/encrypt action occurs during use of the Send Later feature, which
allows remote attackers to obtain sensitive information by sniffing the
network.

Impact
======

A remote attacker who is sniffing the network may be able to obtain
sensitive information when an email that should be encrypted is sent
via the "Send Later with Delay" function.
