Die Open-Source In-Memory-Datebank, Redis, ist ein hochperformanter Object-Cache, der u.a. Webseiten beschleunigen kann. Nun wurde die neue Version 7.0.0 veröffentilcht, die u.a. 2 Security Fixe beinhaltet, ein neues Feature und einige Bugfixes. Zudem wurden Verbesserungen durchgeführt, die die Geschwindigkeit des Caches erhöhen sollen.

Redis 7.0.0 Release Notes

Security Fixes:

• (CVE-2022-24736) 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. This issue affects all versions of Redis.
  [reported by Aviv Yahav].
• (CVE-2022-24735) By exploiting weaknesses in the Lua script execution
  environment, an attacker with access to Redis can inject Lua code that will
  execute with the (potentially higher) privileges of another Redis user.
  [reported by Aviv Yahav].
