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.

The remote host is affected by the vulnerability described in GLSA-202408-05 (Redis: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Redis. Please review the CVE identifiers referenced below     for details.

Tenable has extracted the preceding description block directly from the Gentoo 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.

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)

The remote Redhat Enterprise Linux 8 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: Code injection via Lua script execution environment (CVE-2022-24735)

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

  - Redis before 6cbea7d allows a replica to cause an assertion failure in a primary server by sending a non-     administrative command (specifically, a SET command). NOTE: this was fixed for Redis 6.2.x and 7.x in     2021. Versions before 6.2 were not intended to have safety guarantees related to this. (CVE-2021-31294)

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 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.

    Seiya Nakata and Yudai Fujiwara discovered that Redis incorrectly handled certain specially crafted Lua     scripts. An attacker could possibly use this issue to cause heap corruption and execute arbitrary code.
    (CVE-2022-24834)

    SeungHyun Lee discovered that Redis incorrectly handled specially crafted commands. An attacker could     possibly use this issue to trigger an integer overflow, which might cause Redis to allocate impossible     amounts of memory, resulting in a denial of service via an application crash. (CVE-2022-35977)

    Tom Levy discovered that Redis incorrectly handled crafted string matching patterns. An attacker could     possibly use this issue to cause Redis to hang, resulting in a denial of service. (CVE-2022-36021)

    Yupeng Yang discovered that Redis incorrectly handled specially crafted commands. An attacker could     possibly use this issue to trigger an integer overflow, resulting in a denial of service via an     application crash. (CVE-2023-25155)

    It was discovered that Redis incorrectly handled a specially crafted command. An attacker could possibly     use this issue to create an invalid hash field, which could potentially cause Redis to crash on future     access. (CVE-2023-28856)

    Alexander Aleksandrovi Klimov discovered that Redis incorrectly listened to a Unix socket before setting     proper permissions. A local attacker could possibly use this issue to connect, bypassing intended     permissions. (CVE-2023-45145)

The version of redis installed on the remote host is prior to 6.2.11-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2REDIS6-2023-001 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)

  - 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 can issue a `HRANDFIELD` or     `ZRANDMEMBER` command with specially crafted arguments to trigger a denial-of-service by crashing Redis     with an assertion failure. This problem affects Redis versions 6.2 or newer up to but not including 6.2.9     as well as versions 7.0 up to but not including 7.0.8. Users are advised to upgrade. There are no known     workarounds for this vulnerability. (CVE-2023-22458)

  - 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)

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

  - ** 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.
