In libzypp before 20170803 it was possible to add unsigned YUM repositories without warning to the user that could lead to man in the middle or malicious servers to inject malicious RPM packages into a users system.

This update for libzypp, zypper fixes the following issues :

libzypp security fixes :

PackageProvider: Validate delta rpms before caching (bsc#1091624, bsc#1088705, CVE-2018-7685)

PackageProvider: Validate downloaded rpm package signatures before caching (bsc#1091624, bsc#1088705, CVE-2018-7685)

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

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

libzypp other changes/bugs fixed: Update to version 14.45.17

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)

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

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

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 been loaded (bsc#1096803)

Avoid zombie tar processes (bsc#1076192)

lsof: use '-K i' if lsof supports it (bsc#1099847, bsc#1036304)

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 other changes/bugs fixed: Update to version 1.11.70

Bugfix: Prevent ESC sequence strings from going out of scope (bsc#1092413)

XML <install-summary> attribute `packages-to-change` added (bsc#1102429) </install-summary>

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

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

do not recommend cron (bsc#1079334)
