"The version of openblas installed on the remote host is prior to 0.3.9-1. It is, therefore, affected by a vulnerability
as referenced in the ALAS2R4-2023-001 advisory.

  - An out-of-bounds read flaw was found in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack through
    version 3.10.0, as also used in OpenBLAS before version 0.3.18. Specially crafted inputs passed to these
    functions could cause an application using lapack to crash or possibly disclose portions of its memory.
    (CVE-2021-4048)

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