"This update for libzypp and libsolv fixes the following issues :

Security issues fixed :

  - CVE-2018-20532: Fixed NULL pointer dereference at
    ext/testcase.c (function testcase_read) (bsc#1120629).

  - CVE-2018-20533: Fixed NULL pointer dereference at
    ext/testcase.c (function testcase_str2dep_complex) in
    libsolvext.a (bsc#1120630).

  - CVE-2018-20534: Fixed illegal address access at
    src/pool.h (function pool_whatprovides) in libsolv.a
    (bsc#1120631).

Fixed bugs and enhancements :

  - make cleandeps jobs on patterns work (bnc#1137977)

  - Fixed an issue where libsolv failed to build against
    swig 4.0 by updating the version to 0.7.5 (bsc#1135749). 

  - Virtualization host upgrade from SLES-15 to SLES-15-SP1
    finished with wrong product name shown up (bsc#1131823).

  - Copy pattern categories from the rpm that defines the
    pattern (fate#323785).

  - Enhance scanning /sys for modaliases (bsc#1130161).

  - Prevent SEGV if the application sets an empty TextLocale
    (bsc#1127026).

  - Handle libgpgme error when gpg key is not completely
    read and user hits CTRL + C (bsc#1127220).

  - Added a hint when registration codes have expired
    (bsc#965786).

  - Adds a better handling of an error when verifying any
    repository medium (bsc#1065022).

  - Will now only write type field when probing
    (bsc#1114908).

  - Fixes an issue where zypper has showed the info message
    'Installation aborted by user' while the installation
    was aborted by wicked (bsc#978193).

  - Suppresses reporting `/memfd:` pseudo files
    (bsc#1123843).

  - Fixes an issue where zypper was not able to install or
    uninstall packages when rpm is unavailable
    (bsc#1122471).

  - Fixes an issue where locks were ignored (bsc#1113296).

  - Simplify complex locks so zypper can display them
    (bsc#1112911).

  - zypper will now set `SYSTEMD_OFFLINE=1` during chrooted
    commits (bsc#1118758).

  - no-recommends: Nevertheless consider resolver namespaces
    (hardware, language,..supporting packages)
    (fate#325513).

  - Removes world-readable bit from /var/log/zypp
    (bsc#1099019).

  - Does no longer fail service-refresh on a empty
    repoindex.xml (bsc#1116840).

  - Fixes soname due to libsolv ABI changes (bsc#1115341).

  - Add infrastructure to flag specific packages to trigger
    a reboot needed hint (fate#326451).

This update for zypper 1.14.27 fixes the following issues :

  - bash-completion: add package completion for addlock
    (bsc#1047962)

  - bash-completion: fix incorrect detection of command
    names (bsc#1049826)

  - Offer to change the 'runSearchPackages' config option at
    the prompt (bsc#1119373, FATE#325599)

  - Prompt: provide a 'yes/no/always/never' prompt.

  - Prompt: support '#NUM' as answer to select the NUMth
    option...

  - Augeas: enable writing back changed option values (to
    ~/.zypper.conf)

  - removelocale: fix segfault

  - Move needs-restarting command to subpackage (fixes #254)

  - Allow empty string as argument (bsc#1125415)

  - Provide a way to delete cache for volatile repositories
    (bsc#1053177)

  - Adapt to boost-1.69 requiring explicit casts
    tribool->bool (fixes #255)

  - Show support status in info if not unknown (bsc#764147)

  - Fix installing plain rpm files with `zypper in`
    (bsc#1124897)

  - Show only required info in the summary in quiet mode
    (bsc#993025)

  - Stay with legacy behavior and return
    ZYPPER_EXIT_INF_REBOOT_NEEDED only for patches. We don't
    extend this return code to packages, although they may
    also carry the 'reboot-needed' attribute. The preferred
    way to test whether the system needs to be rebooted is
    `zypper needs-rebooting`. (openSUSE/zypper#237)

  - Skip repository on error (bsc#1123967)

  - New commands for locale management: locales addlocale
    removelocale Inspect and manipulate the systems
    `requested locales`, aka. the languages software
    packages should try support by installing translations,
    dictionaries and tools, as far as they are available.

  - Don't throw, just warn if options are repeated
    (bsc#1123865)

  - Fix detection whether stdout is a tty (happened too
    late)

  - Fix broken --plus-content switch (fixes bsc#1123681)

  - Fix broken --replacefiles switch (fixes bsc#1123137)

  - Extend zypper source-install (fixes bsc#663358)

  - Fix inconsistent results for search (bsc#1119873)

  - Show reboot hint in zypper ps and summary (fixes
    bsc#1120263)

  - Improve handling of partially locked packages
    (bsc#1113296)

  - Fix wrong default values in help text (bsc#1121611)

  - Fixed broken argument parsing for --reposd-dir
    (bsc#1122062)

  - Fix wrong zypp::indeterminate use (bsc#1120463)

  - CLI parser: fix broken initialization enforcing 'select
    by name' (bsc#1119820)

  - zypper.conf: [commit] autoAgreeWithLicenses (=false)
    (fixes #220)

  - locks: Fix printing of versioned locks (bsc#1112911)

  - locks: create and write versioned locks correctly
    (bsc#1112911)

  - patch: --with update may implicitly assume
    --with-optional (bsc#1102261)

  - no-recommends: Nevertheless consider resolver namespaces
    (hardware, language,..supporting packages) (FATE#325513)

  - Optionally run 'zypper search-packages' after 'search'
    (FATE#325599)

  - zypper.conf: Add [search]runSearchPackages config
    variable.

  - Don't iterate twice on --no-cd (bsc#1111319)

  - zypper-log: Make it Python 3 compatible

  - man: mention /etc/zypp/needreboot config file
    (fate#326451, fixes #140)

  - Add `needs-restarting` shell script and manpage
    (fate#326451)

  - Add zypper needs-rebooting command (fate#326451)

  - Introduce new zypper command framefork. Migrated
    commands so far: addlock addrepo addservice clean
    cleanlocks modifyrepo modifyservice ps refresh
    refresh-services removelock removerepo removeservice
    renamerepo repos services

  - MediaChangeReport: fix https URLs causing 2 prompts on
    error (bsc#1110542)
