BIT-VALKEY-2022-24735 Lua scripts can be manipulated to overcome ACL rules in Redis

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 scri...

BIT-VALKEY-2022-24736 A Malformed Lua script can crash Redis

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...

BIT-VALKEY-2022-24834 Heap overflow issue with the Lua cjson library used by Redis

Redis is an in-memory database that persists on disk.

Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. Executing an XAUTOCLAIM command on a stream key in a specific state, with a specially crafted COUNT argument may cause an integer overflow, a subsequent heap...

BIT-VALKEY-2022-35977 Integer overflow in certain command arguments can drive Redis to OOM panic

Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted SETRANGE and SORTRO 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 fixe...

BIT-VALKEY-2022-36021 Redis string pattern matching can be abused to achieve Denial of Service

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.
