"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple
vulnerabilities as referenced in the SUSE-SU-2023:2925-1 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 in-memory database that persists on disk. Authenticated users can use string matching commands
    (like `SCAN` or `KEYS`) with a specially crafted pattern to trigger a denial-of-service attack on Redis,
    causing it to hang and consume 100% CPU time. The problem is fixed in Redis versions 6.0.18, 6.2.11,
    7.0.9. (CVE-2022-36021)

  - Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted
    `SRANDMEMBER`, `ZRANDMEMBER`, and `HRANDFIELD` commands can trigger an integer overflow, resulting in a
    runtime assertion and termination of the Redis server process. This problem affects all Redis versions.
    Patches were released in Redis version(s) 6.0.18, 6.2.11 and 7.0.9. (CVE-2023-25155)

  - 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)

  - Redis is an in-memory database that persists on disk. In Redit 7.0 prior to 7.0.12, extracting key names
    from a command and a list of arguments may, in some cases, trigger a heap overflow and result in reading
    random heap memory, heap corruption and potentially remote code execution. Several scenarios that may lead
    to authenticated users executing a specially crafted `COMMAND GETKEYS` or `COMMAND GETKEYSANDFLAGS`and
    authenticated users who were set with ACL rules that match key names, executing a specially crafted
    command that refers to a variadic list of key names. The vulnerability is patched in Redis 7.0.12.
    (CVE-2023-36824)
