 Kleopatra: Remote code execution — GLSA 202008-21

A vulnerability in Kleopatra allows arbitrary execution of code.

Affected packages

Package                kde-apps/kleopatra on all architectures
Affected versions      < 20.04.3-r1
Unaffected versions    >= 20.04.3-r1


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.


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"
