"This update for feh on Leap 42.1 fixes this security issue :

  - CVE-2017-7875: In wallpaper.c in feh if a malicious
    client pretended to be the E17 window manager, it was
    possible to trigger an out-of-boundary heap write while
    receiving an IPC message. An integer overflow leads to a
    buffer overflow and/or a double free (bsc#1034567).

This update for feh on Leap 42.2 to version 2.18.3 fixes several
issues.

This security issue was fixed on Leap 42.2 :

  - CVE-2017-7875: In wallpaper.c in feh if a malicious
    client pretended to be the E17 window manager, it was
    possible to trigger an out-of-boundary heap write while
    receiving an IPC message. An integer overflow leads to a
    buffer overflow and/or a double free (bsc#1034567).

These non-security issue was fixed on Leap 42.2 :

  - boo#955576: added jpegexiforient

  - Fixed image-specific format specifiers not being updated
    correctly in thumbnail mode window titles

  - Fixed memory leak when closing images opened from
    thumbnail mode

  - Fixed a possible out of bounds read caused by an
    unterminated string when using --output to save images
    in long paths

  - Fixed out of bounds read/write when handling empty or
    broken caption files.

  - Fixed memory leak when saving a filelist or image whose
    target filename already exists.

  - Fixed image-specific format specifiers not being updated
    correctly

  - New key binding: ! - zoom_fill (zoom to fill window, may
    cut off image parts

  - Disable EXIF-based auto rotation by default

  - Added --auto-rotate option to enable auto rotation 

  - Added feh-makefile_app.patch -- fix install location of
    icons

  - Install feh icon (both 48x48 and scalable SVG) to
    /usr/share/icons when running 'make install app=1'

  - Fixed --sort not being respected after the first reload
    when used in conjunction with --reload

  - All key actions can now also be bound to a button by
    specifying them in .config/feh/buttons. However, note
    that button actions can not be bound to keys.

  - Rename 'menu' key action to 'toggle_menu', 'prev' to
    'prev_img' and 'next' to 'next_img'. The old names are
    still supported, but no longer documented.

  - feh now also sets the X11 _NET_WM_PID and
    WM_CLIENT_MACHINE window properties

  - Fixed compilation on systems where HOST_NAME_MAX is not
    defined

  - Also support in-place editing for images loaded via
    libcurl or imagemagick. Results will not be written back
    to disk in this case.

  - Fixed crash when trying to rotate a JPEG image without
    having jpegtran / jpegexiforient installed

  - Handle failing fork() calls gracefully

  - Fixed invalid key/button definitions mis-assigning
    keys/buttons to other actions

  - Added sort mode --sort dirname to sort images by
    directory instead of by name.

  - Added navigation keys next_dir (]) and prev_dir ([) to
    jump to the first image of the nex/previous directory 

  - Fixed toggle_filenames key displaying wrong file numbers
    in multiwindow mode

  - Rescale image when resizing a window and --scale-down or
    --geometry is active.

  - Fixed --keep-zoom-vp not keeping the viewport x/y
    offsets 

  - Fixed w (size_to_image) key not updating window size
    when --scale-down or --geometry is active

  - Added --insecure option to disable HTTPS certificate
    checks

  - Added --no-recursive option to disable recursive
    directory expansion.

  - Improve --scale-down in tiling environments.

  - --action and --action[1..9] now support action titles

  - -f / --filelist: Do not print useless error message when
    a correct filelist file is specified

  - -f / --filelist: Fix bug in '-' / '/dev/stdin' handling
    affecting feh running in ksh and possibly other
    environments

  - Add --xinerama-index option for background setting

  - When removing the last image in slidsehow mode, stay on
    the last (previously second-to-last) image

  - Allow --sort and --randomize to override each other
    (most recently specified option wins) instead of always
    preferring --sort

  - Thumbnail mode: Mark image as processed when executing
    an action (--action) by clicking on an image

  - It is now possible to override feh's idea of the active
    xinerama screen using the --xinerama-index option

  - Removed (undocumented) feature allowing to override
    feh's idea of the active xinerama screen by setting the
    XINERAMA_SCREEN environment variable

  - Removed obsolete gpg macro"
