Doc Text:	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.	Story Points:	---

Description Robb Gatica 2023-10-18 22:31:28 UTC

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.
