Redis core team reports:

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. Specifically: using COMMAND GETKEYS* and validation of key names in ACL rules.

Huang Zhw reports:

On 32-bit versions, Redis BITFIELD command is vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves constructing specially crafted bit commands which overflow the bit offset.

This problem only affects 32-bit versions of Redis.

Redis core team reports:

The wrong order of listen(2) and chmod(2) calls creates a race condition that can be used by another process to bypass desired Unix socket permissions on startup.

Aviv Yahav reports:

CVE-2022-24735

By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis can inject Lua code that will execute with the (potentially higher) privileges of another Redis user.

CVE-2022-24736

An attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process.

The Redis core team reports:

CVE-2022-35977

Integer overflow in the Redis SETRANGE and SORT/SORT_RO commands can drive Redis to OOM panic.

CVE-2023-22458

Integer overflow in the Redis HRANDFIELD and ZRANDMEMBER commands can lead to denial-of-service.

Redis core team reports:

A specially crafted Lua script executing in Redis can trigger a heap overflow in the cjson and cmsgpack libraries, and result in heap corruption and potentially remote code execution.

The Redis core team reports:

CVE-2023-25155

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

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.

Redis core team reports:

Authenticated users can use the HINCRBYFLOAT command to create an invalid hash field that may later crash Redis on access.

< 7.0.11

< 6.2.12

< 6.0.19

Redis Development team reports:

Redis 4.0 or newer uses a configurable limit for the maximum supported bulk input size. By default, it is 512MB which is a safe value for all platforms. If the limit is significantly increased, receiving a large request from a client may trigger several integer overflow scenarios, which would result with buffer overflow and heap corruption.

< 6.2.0

< 6.0.11

< 5.0.11

Redis team reports:

The redis-cli history file (in linenoise) is created with the default OS umask value which makes it world readable in most systems and could potentially expose authentication credentials to other users.

< 3.2.3

oCERT reports:

A variety of programming languages suffer from a denial-of-service (DoS) condition against storage functions of key/value pairs in hash data structures, the condition can be leveraged by exploiting predictable collisions in the underlying hashing algorithms.

The issue finds particular exposure in web server applications and/or frameworks. In particular, the lack of sufficient limits for the number of parameters in POST requests in conjunction with the predictable collision properties in the hashing functions of the underlying languages can render web applications vulnerable to the DoS condition. The attacker, using specially crafted HTTP requests, can lead to a 100% of CPU usage which can last up to several hours depending on the targeted application and server performance, the amplification effect is considerable and requires little bandwidth and time on the attacker side.

The condition for predictable collisions in the hashing functions has been reported for the following language implementations: Java, JRuby, PHP, Python, Rubinius, Ruby. In the case of the Ruby language, the 1.9.x branch is not affected by the predictable collision condition since this version includes a randomization of the hashing function.

The vulnerability outlined in this advisory is practically identical to the one reported in 2003 and described in the paper Denial of Service via Algorithmic Complexity Attacks which affected the Perl language.
