01 Mar 2023 — 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. A vulnerability was found in Redis.

20 Jan 2023 — 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. • https://github.com/redis/redis/commit/1ec82e6e97e1db06a72ca505f9fbf6b981f31ef7 • CWE-190: Integer Overflow or Wraparound •

20 Jan 2023 — 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.

21 Oct 2022 — ** 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. • https://github.com/redis/redis/commit/0bf90d944313919eb8e63d3588bf63a367f020a3 • CWE-404: Improper Resource Shutdown or Release •
CVSS: 5.5EPSS: 0%CPEs: 12EXPL: 1CVE-2022-24736 – A Malformed Lua script can crash Redis

27 Apr 2022 — Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, 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 problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.

27 Apr 2022 — Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. The Lua script execution environment in Redis provides some measures that prevent a script from creating side effects that persist and can affect the execution of the same, or different script, at a later time.

04 Oct 2021 — Redis is an open source, in-memory database that persists on disk. An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14.

04 Oct 2021 — Redis is an open source, in-memory database that persists on disk. The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. This is a result of a vulnerability in the underlying hiredis library which does not perform an overflow check before calling the calloc() heap allocation function. This issue only impacts systems with heap allocators that do not perform their own overflow checks.

04 Oct 2021 — Redis is an open source, in-memory database that persists on disk. When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). An attacker delivering specially crafted requests over multiple connections can cause the server to allocate significant amount of memory. Because the same parsing mechanism is used to handle authentication re... • https://github.com/redis/redis/commit/5674b0057ff2903d43eaff802017eddf37c360f8 • CWE-770: Allocation of Resources Without Limits or Throttling •
