The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6531-1 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 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 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 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. On startup, Redis begins listening on a Unix socket     before adjusting its permissions to the user-provided configuration. If a permissive umask(2) is used,     this creates a race condition that enables, during a short period of time, another process to establish an     otherwise unauthorized connection. This problem has existed since Redis 2.6.0-RC1. This issue has been     addressed in Redis versions 7.2.2, 7.0.14 and 6.2.14. Users are advised to upgrade. For users unable to     upgrade, it is possible to work around the problem by disabling Unix sockets, starting Redis with a     restrictive umask, or storing the Unix socket file in a protected directory. (CVE-2023-45145)

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