A heap-based buffer overflow flaw was found in Redis. This flaw allows a local authenticated attacker user or attacker to execute a specially crafted Lua script in Redis. This attack triggers a heap overflow in the cjson and cmsgpack libraries, resulting in heap corruption and potential remote code execution.

A flaw was found in Redis, an in-memory database that persists on disk. On startup, Redis listens 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.

A flaw was found in Redis. This flaw allows authenticated users to trigger a denial of service by using specially crafted, long string match patterns on supported commands such as KEYS, SCAN, PSUBSCRIBE, FUNCTION LIST, COMMAND LIST, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.

A flaw was found in Redis. This flaw allows an authenticated user to use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may lead to remote code execution. The problem exists in all versions of Redis with Lua scripting.

A flaw was found in the Redis server. This flaw allows an authenticated user to use a specially crafted Lua script to manipulate the garbage collector, potentially leading to remote code execution.
