Affected Products:

  * SUSE Linux Enterprise Server 16.0
  * SUSE Linux Enterprise Server for SAP applications 16.0

  
  
An update that solves seven vulnerabilities, contains two features and has five
fixes can now be installed.

## Description:

This update for zypper, libzypp, libsolv fixes the following issues:

Changes in zypper:

Update to 1.14.98:

  * Transactional systems: Delegate rw-commands to transactional-wrapper if
    available (jsc#PED-13680, jsc#PED-15607) On a transactional system where the
    root filesystem is mounted read-only, zypper commands that modify the system
    cannot be executed directly. If the system provides a transactional-wrapper
    utility, zypper will automatically attempt to invoke it. The wrapper
    transparently executes the zypper command within a new, writable snapshot
    and manages the lifecycle of that snapshot based on the command's exit
    status. On transactional systems lacking a transactional-wrapper, users must
    manually invoke specialized tools -such as transactional-update- to install,
    update, or remove software.
  * Add --filter-version-change to zypper lu. Adds filtering by version change
    significance to reduce noise in update listings. Supports levels: rebuild
    (hides rebuild-only changes) and package (hides all release-only changes).
  * Autorefresh ris-services the way as plugin-services (bsc#1246504) It's
    actually wrong to treat service refreshes different depending on the service
    type. For the purpose of a service it makes no difference how the data about
    the repos to use are acquired.

Changes in libzypp:

Updated to 17.38.13:

  * A .repo files "path=" entry must not refer to a location outside the repo
    (bsc#1267874, CVE-2026-44942) A "path=" entry may solely denote a sub-
    directory of the baseurl where the metadata are located. A relative path
    trying to access data outside the baseurl is reported and sanitized.
  * Repo "keyhint" must denote a filename, no path (bsc#1267426, CVE-2026-44941)
  * Fix potential crash on malformed or malicious repository metadata (fixes
    #740)
  * Repo metadata: discard entries referring to a location outside the repo
    (bsc#1259802, CVE-2026-25707) Mirroring those data locally would refer to a
    location outside the repo's local cache directory. Those data entries are
    reported and discarded.
  * zypp.conf: Allow [env] section to add environment variables. This feature is
    designed to enable environment-specific settings or debugging options over
    an extended period. See zypp.conf(5).
  * Prevent configured scripts from escaping the sigcheck directory
    (bsc#1265223, CVE-2026-44933)
  * StringV: guard hasPrefix/hasPrefixCI against reading past the view end
    (fixes #735)
  * Mandatory signature verification plugin support (PED#11922)
  * Fix purge-kernel -rc kernel handling (bsc#1239718)
  * Explicitly_set_pool_DISTTYPE_RPM (fixes #726)
  * Check for trusted key updates when updating the general keyring
    (bsc#1259706)
  * Support multiple MirroredOrigin authorities (bsc#1253193)
  * Workaround doxygen bug: doxygen/doxygen#12057
  * libzypp.spec: Add missing graphviz-gd BuildRequires (boo#1259842)

Changes in libsolv:

Updated to 0.7.39:

  * fix solv_chksum_free segfault when called with a NULL pointer
  * made repo_add_solv more robust against corrupt files [bsc#1265935]
    [CVE-2026-9149]
  * fix potential buffer overflow when verifying EdDSA signatures [bsc#1266039]
    [CVE-2026-48863]
  * added limit checks in multiple places to catch overflows
  * reduce the size of the language id cache
  * fixed Debian canon selection
  * fixed dbpath detection in repo_rpmdb_librpm
  * reduced stack usage in repo page compression (needed for musl)
  * fix parsing of sha512 checksums in debian repositories [bsc#1265938]
    [CVE-2026-9150]
  * improve speed of dirpool_add_dir makeing parsing of filelists.xml twice as
    fast
  * fix parsing of recommends in the old Mandriva synthesis format
