Damian Poddebniak, Christian Dresen, Jens Müller, Fabian Ising, Sebastian Schinzel, Simon Friedberger, Juraj Somorovsky, and Jörg Schwenk discovered that the KMail application of KDE PIM could be made to leak the plaintext of S/MIME encrypted emails when retrieving external content in emails. Under certain configurations, if a user were tricked into opening a specially crafted email, an attacker could possibly use this issue to obtain the plaintext of an encrypted email. This update mitigates the issue by preventing KMail from automatically loading external content. (CVE-2017-17689) Jens Müller, Marcus Brinkmann, Damian Poddebniak, Sebastian Schinzel, and Jörg Schwenk discovered that the KMail application of KDE PIM could be made to leak the plaintext of S/MIME or PGP encrypted emails. If a user were tricked into replying to a specially crafted email, an attacker could possibly use this issue to obtain the plaintext of an encrypted email. (CVE-2019-10732) It was discovered that the KMail application of KDE PIM could be made to attach files to an email without the user's knowledge. If a user were tricked into sending an email created by a specially crafted "mailto" link, an attacker could possibly use this issue to obtain sensitive files. This update mitigates the issue by displaying a warning to the user when files are attached in this way. (CVE-2020-11880) It was discovered that the Account Wizard application of KDE PIM used HTTP rather than HTTPS when retrieving certain email server configurations. An attacker could possibly use this issue to cause email clients to use an attacker-controlled email server. This issue only affected Ubuntu 16.04 LTS. (CVE-2024-50624)
