In KDE Frameworks KConfig before 5.61.0, malicious desktop files and configuration files lead to code execution with minimal user interaction. This relates to libKF5ConfigCore.so, and the mishandling of .desktop and .directory files, as demonstrated by a shell command on an Icon line in a .desktop file.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

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)** &ndash;
    `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** &ndash; 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** &ndash; 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/confi     g/kdeglobals`,     `/usr/share/kde-settings/kde-profile/minimal/share/confi     g/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/baloofi     lerc`: Delete the commented-out `folders` setting that     attempts to call `xdg-user-dir`.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4100-1 advisory.

    It was discovered that KConfig and KDE libraries have a vulnerability where an attacker could hide     malicious code under desktop and configuration files. (CVE-2019-14744)

    It was discovered that KConfig allows remote attackers to write to arbitrary files via a ../ in a filename     in an archive file. (CVE-2016-6232)

The remote host is affected by the vulnerability described in GLSA-201908-07 (KDE KConfig: User-assisted execution of arbitrary code)

    A vulnerability was discovered in KDE KConfig&rsquo;s handling of .desktop       and .directory files.
  Impact :

    An attacker could entice a user to execute a specially crafted .desktop       or .directory file possibly resulting in execution of arbitrary code with       the privileges of the process.
  Workaround :

    There is no known workaround at this time.

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.)

Dominik Penner discovered a flaw in how KConfig interpreted shell commands in desktop files and other configuration files. An attacker may trick users into installing specially crafted files which could then be used to execute arbitrary code, e.g. a file manager trying to find out the icon for a file or any application using KConfig. Thus the entire feature of supporting shell commands in KConfig entries has been removed.

For Debian 8 'Jessie', this problem has been fixed in version 4:4.14.2-5+deb8u3.

We recommend that you upgrade your kde4libs packages.

New kdelibs packages are available for Slackware 14.2 and -current to fix a security issue.

The KDE Community has released a security announcement :

The syntax Key[$e]=$(shell command) in *.desktop files, .directory files, and configuration files (typically found in ~/.config) was an intentional feature of KConfig, to allow flexible configuration. This could however be abused by malicious people to make the users install such files and get code executed even without intentional action by the user.

Dominik Penner discovered that KConfig, the KDE configuration settings framework, supported a feature to define shell command execution in .desktop files. If a user is provided with a malformed .desktop file (e.g. if it's embedded into a downloaded archive and it gets opened in a file browser) arbitrary commands could get executed. This update removes this feature.
