Synopsis
========

A vulnerability in Kleopatra allows arbitrary execution of code.

Background
==========

Kleopatra is a certificate manager and a universal crypto GUI. It
supports managing X.509 and OpenPGP certificates in the GpgSM keybox
and retrieving certificates from LDAP servers.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  kde-apps/kleopatra         < 20.04.3-r1            >= 20.04.3-r1

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

Kleopatra did not safely escape command line parameters provided by
URLs, which it configures itself to handle.

Impact
======

A remote attacker could entice a user to process a specially crafted
URL via openpgp4fpr handler, possibly resulting in execution of
arbitrary code with the privileges of the process, or cause a Denial of
Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Kleopatra users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=kde-apps/kleopatra-20.04.3-r1"
