Leslie ---------- Forwarded Message ---------- Subject: KDE Project Security Advisory: messagelib: HTML email caopebrowser window automatically Date: 2018-11-28, 12:46:50 From: Albert Astals Cid &lt;aacid(a)kde.org&gt; To: kde-announce(a)kde.org KDE Project Security Advisory ============================= Title: messagelib: HTML email can open browser window automatically Risk Rating: Low CVE: CVE-2018-19516 Versions: KDE Applications < 18.12.0 Date: 28 November 2018 Overview ======== messagelib is the library used by KMail to display emails. messagelib by default displays emails as plain text, but gives the user an option to "Prefer HTML to plain text" in the settings and if that option is not enabled there is way to enable HTML display when an email contains HTML. Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML. This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings. This means that the owners of the servers referred in the email can see in their access logs your IP address. Workaround ========== Do not enable "Prefer HTML to plain text" in KMail settings. Solution ======== Update to KDE Applications >= 18.12.0 Or apply the following patch: https://cgit.kde.org/messagelib.git/commit/?id=34765909cdf8e55402a8567b48fb… Credits ======= Thanks to Jany Belluz for the report and to Laurent Montel for the fix. -------------------------------------------------------
