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

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.
