Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:4096-1 advisory.

Security issue fixed:

- invalidating legacy libzypp unsigned-repository cache state [LIBZYPP-LEGACY-CACHE-01] (bsc#1274625).
- hasCredentials() requires both username AND password to be non-empty (bsc#1273242).
- GPG Key hints in repoindex.xml require at least a long id to allow auto-import (bsc#1271730).

Non security issues fixed:

- Econf parser adds tags in drop-in files outside any section to [main] (bsc#1272534).
- libzypp: X-ZYpp-AnonymousId header anomaly (bsc#1268321).
- 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).
- dependency issue for package 'python3-vsts-cd-manager' after starting the upgrade (bsc#1261038).

Changes for libzypp:

- Update to version 17.38.15:

- Prevent libgpgme from launching gpg-agents; we don't need them.
- defaultLoadSystem: Hand out the ZYpp::Ptr as return value.
- Replace popen cat/zcat with solv_xfopen for testcase loaders (fixes #749)
- zypp: Improve Testcase Loading for MCP Tools.
- spec: Remove useless %bcond visibility_hidden (is always ON in cmake)
- zypp.conf: add solver.NoUpdateProvide (default: false) option.

Changes for zypper:

- Update to version 1.14.101.
