Description:

   This update for libzypp, zypper provides the following fixes:

   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)

     (bsc#1045735, CVE-2017-9269)

     (bsc#1038984, CVE-2017-7436)

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