CVE-2022-24834 - 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 problem exists in all versions of Redis with Lua scripting support, starting from 2.6, and affects only authenticated and authorized users.

CVE-2023-45145 - 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.

Upstream have released version 7.0.14/7.2.2 to fix CVE-2023-45145.

A vulnerability was found in Redis. This flaw allows authenticated users to use the HINCRBYFLOAT command to create an invalid hash field that may crash Redis on access.

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.

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.

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 GETKEYSANDFLAGSand 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.

Redis is an open source, in-memory database that persists on disk. In versions starting from 7.0.0 to before 8.0.2, a stack-based buffer overflow exists in redis-check-aof due to the use of memcpy with strlen(filepath) when copying a user-supplied file path into a fixed-size stack buffer. This allows an attacker to overflow the stack and potentially achieve code execution. This issue has been patched in version 8.0.2.
