kdelibs-4.14.38-15.fc30 and kde-settings-30.3-1.fc30

FEDORA-2019-a746ac9c89 created by kkofler 5 years ago for Fedora 30

This update fixes CVE-2019-14744 (kconfig arbitrary shell code execution) in the compatibility library kdelibs 4 used by legacy applications (not yet ported to KDE Frameworks 5). The included kde-settings update removes obsolete settings that conflict with the security fix and are no longer needed (see below for details).

The full list of fixes in the kdelibs 4 build:

  • fixes CVE-2019-14744 (#1740138, #1740140)kconfig: malicious .desktop files (and others) would execute code. KConfig had a well-meaning feature that allowed configuration files to execute arbitrary shell commands. Unfortunately, this could be abused by untrusted .desktop files to execute arbitrary code as the target user, without the user even running the .desktop file. Therefore, this update removes that ill-fated feature. (Patch from upstream: kf5-kconfig fix by David Faure, kdelibs 4 backport by Kai Uwe Broulik.)
  • fixes #917848 – removes support for the gamin file watching service which is unmaintained and buggy and can lead to application lockups. KDirWatch now relies exclusively on inotify (directly). (Packaging fix by Rex Dieter.)
  • fixes #1730770 – removes an unused dependency on the obsolete xf86misc library. (Packaging fix by Kevin Kofler.)

The fixes in the kde-settings build remove settings that were calling xdg-user-dir, because the above CVE-2019-14744 fix drops support for running shell commands from configuration files from KConfig and because the settings are all no longer needed (because they either only reproduce default behavior or were commented out):

  • /usr/share/kde-settings/kde-profile/default/share/config/kdeglobals, /usr/share/kde-settings/kde-profile/minimal/share/config/kdeglobals: Remove the [Paths] section. The Desktop and Documents directories that were set there are already detected by default by kdelibs 4 (it has native support for xdg-user-dirs and does not need the external xdg-user-dir command invocation), and now also by kdelibs3 >= 3.5.10-101 (which has native xdg-user-dirs support backported). The Trash setting was already commented out.
  • /usr/share/kde-settings/kde-profile/default/xdg/baloofilerc: Delete the commented-out folders setting that attempts to call xdg-user-dir.
