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.

    It was discovered that there were a number of issues in Redis, a popular     key-value database:

     * CVE-2023-45145: On startup, Redis began listening on a Unix        socket before adjusting its permissions to the user-provided        configuration. If a permissive umask(2) was used, this created a        race condition that enabled, during a short period of time,        another process to establish an otherwise unauthorized connection.

     * CVE-2023-28856: Authenticated users could have used the        HINCRBYFLOAT command to create an invalid hash field that would        have crashed the Redis server on access.

     * CVE-2023-25155: 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.

     * CVE-2022-36021: 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.

     * CVE-2022-24834: A specially-crafted Lua script executing in Redis        could have triggered a heap overflow in the cjson and cmsgpack        libraries and result in heap corruption and potentially remote        code execution.


    For Debian 11 bullseye, these problems have been fixed in version     5:6.0.16-1+deb11u3.

    We recommend that you upgrade your redis packages.

An update of the redis package has been released.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - redis: heap overflow in the lua cjson and cmsgpack libraries (CVE-2022-24834)

  - redis: crash in sigsegvHandler debug function (CVE-2022-3647)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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)

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.

    ** 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.
