A command injection vulnerability was discovered in the `rpmuncompress` utility of RPM. When extracting certain archive formats (ZIP, 7z, GEM) to a specified destination directory, the tool inserts the archive's top-level folder name into a shell command without properly sanitizing it. A specially crafted archive containing shell metacharacters in its folder name can execute arbitrary commands as the user running the extraction.

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21856-1 advisory.

    Changes in rpm:

    - split imaevmsign plugin into a multibuild flavor

    Changes in rpm:

    - Add Requires: (rpm-plugin-selinux if selinux-policy)
    - harden ndb code [bsc#1269584] [CVE-2026-44605]
    - split all plugins into subpackages
      * this allows for an easy way to get rid of a plugin, it's also         what other distributions do
    - make the imaevmsign plugin build in a multibuild flavor
    - rpm2archive: use size 0 for hardlinked files as bnew versions of       gnu tar reject non-zero sizes [bsc#1269150]
    - backport fix for add_sysuser macro [bsc#1269571]
    - backport rpmuncompress security fix [bsc#1268747] [CVE-2026-44604]
    - switch from rpmpgp_legacy to libpgpr
      * multiple bug fixes, support for v5 and v6 signatures
    - turn on imaevm file signature support and move the imaevm code       that needs the libimaevm library into a plugin. Put this       plugin into a new rpm-imaevmsign subpackage. [jsc#PED-7246]
    - Fix unexpected EOF when using rpmbuild to install ELF binaries       due to syntax error in /usr/lib/rpm/brp-strip. (boo#1259215)
    - Remove /var/lib/rpm migration scripting, retain an error if old       location is found
    - Use systemd-tmpfiles to create & maintain /var/lib/rpm symlink       (boo#1253139)
    - flush scriptlet notification messages in --runposttrans
      * needed to fix leaking tmp files [bsc#1218459]
      * added rpm_flushes_runposttrans provides for libzypp
