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.

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-2026:3600-1 advisory.

    Security issues fixed:

    - CVE-2026-44605: heap buffer overflow in NDB database backend due to unchecked 32-bit arithmetic when     parsing the slot       table (bsc#1269584).

    Other updates and bugfixes:

    - Fix `libelf` handle not being closed, resulting in build errors when using a NFS buildroot     (bsc#1240054).

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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)
