Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-164 advisory.

- Redis is an in-memory database that persists on disk. Starting in version 7.0.8 and prior to version 7.0.10, authenticated users can use the MSETNX command to trigger a runtime assertion and termination of the Redis server process. The problem is fixed in Redis version 7.0.10. (CVE-2023-28425)

- Redis is an open source, in-memory database that persists on disk. Authenticated users can use the `HINCRBYFLOAT` command to create an invalid hash field that will crash Redis on access in affected versions. This issue has been addressed in in versions 7.0.11, 6.2.12, and 6.0.19. Users are advised to upgrade. There are no known workarounds for this issue. (CVE-2023-28856)

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

Solution

Run 'dnf update redis6 --releasever 2023.0.20230503' to update your system.
