The mongo-go-driver repository contains CGo bindings for GSSAPI (Kerberos) authentication on Linux and macOS. The C wrapper implementation contains a heap out-of-bounds read vulnerability due to incorrect assumptions about string termination in the GSSAPI standard. Since GSSAPI buffers are not guaranteed to be null-terminated or have extra padding, this results in reading one byte past the allocated heap buffer.

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:21276-1 advisory.

    Changes in apptainer:

    - Enable building of SUID starter for SLES 15 (jsc#PED-16347).
      * Security fix for CVE-2026-2303 (bsc#1270529):
        Heap Out-of-Bounds Read in GSSAPI Error Handling in         go.mongodb.org/mongo-driver. The dependency on mongo-driver         has been removed with this version of apptainer.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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