    Update Information:
    
    This update fixes **CVE-2019-14744 (kconfig arbitrary shell code execution)** in
    the KDE 3 compatibility version of kdelibs used by legacy KDE 3 applications.
    The full list of fixes in this `kdelibs3` build:  * fixes **CVE-2019-14744** -
    `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. (Backported by Kevin Kofler from upstream: `kf5-kconfig` fix by David
    Faure, `kdelibs` 4 backport by Kai Uwe Broulik.) * adds native support for
    **xdg-user-dirs** for *Desktop* and *Documents*, without shelling out to `xdg-
    user-dir` from the config file. This is needed due to the above security fix.
    (This feature was previously implemented in the Fedora `kde-settings` by
    shelling out to `xdg-user-dir` from the config file using the KConfig feature
    removed above.) (Backported by Kevin Kofler from Trinity Desktop / Timothy
    Pearson.) * fixes a **KJS double-free** that could crash legacy KDE 3
    applications such as Quanta Plus when trying to execute JavaScript. (Backported
    by OpenSUSE / Wolfgang Bauer from Trinity Desktop / Timothy Pearson.)
    --------------------------------------------------------------------------------

    * Sat Aug 10 2019 Kevin Kofler  - 3.5.10-101
    - Backport CVE-2019-14744 fix by David Faure and Kai Uwe Broulik from kdelibs 4
    - Backport native xdg-user-dirs support by Timothy Pearson from Trinity (needed
      to fix the regression that would otherwise result from the above security fix)
    - Backport KJS double-free fix by Timothy Pearson (backport by wbauer/OpenSUSE)
