libzypp security fixes:

CVE-2018-7685: Validate RPMs before caching (bsc#1091624, bsc#1088705)

CVE-2017-9269: Be sure bad packages do not stay in the cache
 (bsc#1045735)

CVE-2017-7435, CVE-2017-7436, CVE-2017-9269: Fix repo gpg check
 workflows, mainly for unsigned repos and packages (bsc#1045735,
 bsc#1038984)

libzypp changes:

RepoManager: Explicitly request repo2solv to generate application pseudo
 packages.

Prefer calling 'repo2solv' rather than 'repo2solv.sh'.

libzypp-devel should not require cmake. (bsc#1101349)

HardLocksFile: Prevent against empty commit without Target having been
 loaded. (bsc#1096803)

Avoid zombie tar processes. (bsc#1076192)

man: Make sure that '--config FILE' affects zypper.conf, not zypp.conf.
 (bsc#1100028)

ansi.h: Prevent ESC sequence strings from going out of scope.
 (bsc#1092413)

RepoInfo: add enum GpgCheck for convenient gpgcheck mode handling
 (bsc#1045735)

repo refresh: Re-probe if the repository type changes (bsc#1048315)

Use common workflow for downloading packages and srcpackages. This
 includes a common way of handling and reporting gpg signature and
 checks. (bsc#1037210)

PackageProvider: as well support downloading SrcPackage (for bsc#1037210)

Adapt to work with GnuPG 2.1.23 (bsc#1054088) Use 'gpg --list-packets'
 to determine the keyid to verify a signature.

Handle http error 502 Bad Gateway in curl backend (bsc#1070851)

zypper security fixes:

Improve signature check callback messages (bsc#1045735, CVE-2017-9269)

add/modify repo: Add options to tune the GPG check settings
 (bsc#1045735, CVE-2017-9269)

Adapt download callback to report and handle unsigned packages
 (bsc#1038984, CVE-2017-7436)

zypper changes:

download: fix crash when non-package types are passed as argument
 (bsc#1037210)

XML attribute `packages-to-change` added (bsc#1102429)");
