** DISPUTED ** A vulnerability, which was classified as problematic, was found in Redis up to 6.2.7/7.0.5. Affected is the function sigsegvHandler of the file debug.c of the component Crash Report. The manipulation leads to denial of service. The complexity of an attack is rather high. The exploitability is told to be difficult. The real existence of this vulnerability is still doubted at the moment. Upgrading to version 6.2.8 and 7.0.6 is able to address this issue. The patch is identified as 0bf90d944313919eb8e63d3588bf63a367f020a3. It is recommended to apply a patch to fix this issue. VDB-211962 is the identifier assigned to this vulnerability. NOTE: The vendor claims that this is not a DoS because it applies to the crash logging mechanism which is triggered after a crash has occurred.

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0037 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2022-24834:
    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-2022-36021:
    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-2022-3647:
    ** DISPUTED ** A vulnerability, which was classified as problematic, was found in Redis. Affected is the     function sigsegvHandler of the file debug.c of the component Crash Report. The manipulation leads to     denial of service. The real existence of this vulnerability is still doubted at the moment. The name of     the patch is 0bf90d944313919eb8e63d3588bf63a367f020a3. It is recommended to apply a patch to fix this     issue. VDB-211962 is the identifier assigned to this vulnerability. NOTE: The vendor claims that this is     not a DoS because it applies to the crash logging mechanism which is triggered after a crash has occurred.

    CVE-2023-25155:
    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-2023-28856:
    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-2023-36824:
    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-2023-41053:
    Redis is an in-memory database that persists on disk. Redis does not correctly identify keys accessed by     `SORT_RO` and as a result may grant users executing this command access to keys that are not explicitly     authorized by the ACL configuration. The problem exists in Redis 7.0 or newer and has been fixed in Redis     7.0.13 and 7.2.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.

    CVE-2023-45145:
    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.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - ** DISPUTED ** A vulnerability, which was classified as problematic, was found in Redis up to 6.2.7/7.0.5.

An update of the redis package has been released.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-154 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)
