A flaw was found in the RPM Package Manager (RPM). A local user could be affected by a heap buffer overflow vulnerability when processing a specially crafted NDB database file. This issue arises from an error in how RPM handles certain calculations during file parsing, leading to an incorrect memory allocation. An attacker could leverage this to cause a denial of service, making the system unavailable.

According to the versions of the rpm packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

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

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1991 advisory.

    A heap buffer overflow exists in RPM's NDB database backend (lib/backend/ndb/rpmpkg.c) due to unchecked     32-bit arithmetic when parsing the slot table. The slotnpages value is read directly from the on-disk NDB     header and used in a 32-bit multiplication (slotnpages * (PAGE_SIZE / SLOT_SIZE)) to size a heap     allocation. A crafted Packages.db can supply a slotnpages value that wraps this product to a small number,     causing xcalloc to allocate an undersized buffer. The subsequent loop iterates over the full unwrapped     page count, writing pkgslot entries past the heap boundary before per-slot validation runs. Exploitation     requires the victim to open a crafted NDB database file with RPM tooling, and NDB is not the default     backend in Fedora or RHEL (both default to sqlite). (CVE-2026-44605)
