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.
