The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3537 advisory.- Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. (CVE-2022-40982)
- Unauthorized error injection in Intel(R) SGX or Intel(R) TDX for some Intel(R) Xeon(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access. (CVE-2022-41804)
- Improper access control in some 3rd Generation Intel(R) Xeon(R) Scalable processors may allow a privileged user to potentially enable information disclosure via local access. (CVE-2023-23908)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
