"The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the
FEDORA-2023-68ae37fca3 advisory.

  - Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted
    `SETRANGE` and `SORT(_RO)` commands can trigger an integer overflow, resulting with Redis attempting to
    allocate impossible amounts of memory and abort with an out-of-memory (OOM) panic. The problem is fixed in
    Redis versions 7.0.8, 6.2.9 and 6.0.17. Users are advised to upgrade. There are no known workarounds for
    this vulnerability. (CVE-2022-35977)

  - Redis is an in-memory database that persists on disk. Authenticated users can issue a `HRANDFIELD` or
    `ZRANDMEMBER` command with specially crafted arguments to trigger a denial-of-service by crashing Redis
    with an assertion failure. This problem affects Redis versions 6.2 or newer up to but not including 6.2.9
    as well as versions 7.0 up to but not including 7.0.8. Users are advised to upgrade. There are no known
    workarounds for this vulnerability. (CVE-2023-22458)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
