Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers which can result in integer overflow that leads to heap overflow and potential remote code execution. This issue has been patched in version 7.0.15 and 7.2.4.

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.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-528 advisory.

    2024-02-29: CVE-2023-45145 was added to this advisory.

    Redis is an in-memory database that persists on disk. Redis incorrectly handles resizing of memory buffers     which can result in integer overflow that leads to heap overflow and potential remote code execution. This     issue has been patched in version 7.0.15 and 7.2.4. (CVE-2023-41056)

    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.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5610 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. 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)

  - 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.
