"The remote SUSE Linux SLES15 / SLES_SAP15 host has a package installed that is affected by multiple vulnerabilities as
referenced in the SUSE-SU-2023:3407-1 advisory.

  - Redis is an in-memory database that persists on disk. A specially crafted Lua script executing in Redis
    can trigger a heap overflow in the cjson library, and result with heap corruption and potentially remote
    code execution. The problem exists in all versions of Redis with Lua scripting support, starting from 2.6,
    and affects only authenticated and authorized users. The problem is fixed in versions 7.0.12, 6.2.13, and
    6.0.20. (CVE-2022-24834)

  - 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.");
