Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 38 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-7228464f28 advisory.

 This release mainly focuses on the detection of the new Zenbleed (CVE-2023-20593) vulnerability, among few other changes that were in line waiting for a release:

 * feat: detect the vulnerability and mitigation of Zenbleed (CVE-2023-20593)
 * feat: add the linux-firmware repository as another source for CPU microcode versions
 * feat: arm: add Neoverse-N2, Neoverse-V1 and Neoverse-V2
 * fix: rewrite SQL to be sqlite3 >= 3.41 compatible ([#443](https://github.com/speed47/spectre-meltdown- checker/issues/443))
 * fix: a /devnull file was mistakenly created on the filesystem
 * fix: fwdb: ignore MCEdb versions where an official Intel version exists (fixes [#430](https://github.com/speed47/spectre-meltdown-checker/issues/430))


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

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

Solution

Update the affected spectre-meltdown-checker package.
