(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 <install-summary> attribute `packages-to-change` added (bsc#1102429) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
