Summary
Security update for libzypp, zypper
Details

This update for libzypp, zypper fixes the following issues:

Security issue fixed:

  • invalidating legacy libzypp unsigned-repository cache state [LIBZYPP-LEGACY-CACHE-01] (bsc#1274625).

Non security issues fixed:

  • Econf parser adds tags in drop-in files outside any section to [main] (bsc#1272534).
  • Need zypper option to disable services to fix Dockerfile builds in OBS (bsc#1257249).
  • zypper loads repository data and installed packages prior to checking for required arguments (bsc#1274091).
  • Zypper patch doesn't give enough details about conflicts (bsc#1277790).

Changes for libzypp:

Update to version 17.38.1:

  • Prevent libgpgme from launching gpg-agents; we don't need them.
  • defaultLoadSystem: Hand out the ZYpp::Ptr as return value.
  • Log all solver problem rules (bsc#1277790) The log contains the most relevant problem rule, but sometimes it helps to know all rules associated with this problem. zypper shows them on demand as 'detail'. The log now remembers them as well.
  • Replace popen cat/zcat with solv_xfopen for testcase loaders (fixes #749)
  • repoGpgCheck: Strictly follow the repo_gpgcheck setting (bsc#1274625) There's been a legacy exception for unsigned repositories which were explicitly accepted in the past. After switching the repo_gpgcheck from off to on, they were allowed to stay unsigned until a first signed version was retrieved. From there on the handling was strict. Now the handling is strict as soon as the repo_gpgcheck turned on. The next set of metadata retrieved must be signed.
  • Iniparser: each new file starts in the unnamed section (bsc#1272534)
  • Fix hasCredentials() to require both username AND password to be non-empty (bsc#1273242) This avoids an unnecessary 2nd 401 response sending just the username in case the username but no password is known. Now it immediately fetches the credentials from disk if no password is known.
  • GPG Key hints in repoindex.xml require at least a long id to allow auto-import (bsc#1271730) The short Id (32bit/8byte) is not considered to be a safe identifier for a gpg key. A long id (64bit/16byte) or even better the full fingerprint is needed to identify the key.
  • zypp: Improve Testcase Loading for MCP Tools.

Changes for zypper:

Update to version 1.14.99:

  • Show solver problem details per default in not-interactive mode (bsc#1277790) This way they see all details when capturing zypper's output because the (d)etail button can't be pressed in not-interactive mode.
  • Add --servicesd-dir global option to relocate /etc/zypp/services.d (bsc#1257249)
  • info: check for missing positional args before systemSetup (bsc#1274091)
  • Remove deprecated installRecommends option from zypper.conf. The system wide default for all libzypp based applications is defined in zypp.conf(5). It is not recommended to define this in zypper exclusively.
