Title:	Kleopatra: Remote code execution
Date:	08/30/2020
Bugs:	#739556
ID:	202008-21

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	Architecture(s)
kde-apps/kleopatra	< 20.04.3-r1	>= 20.04.3-r1	All supported architectures

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"
