Descriptions
Redis is an open source, in-memory database that persists on disk. Authenticated users can 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 crash. This problem has been fixed in Redis versions 6.2.16, 7.2.6, and 7.4.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
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.
It was discovered that Redis incorrectly handled certain memory operations during pattern matching. An attacker could possibly use this issue to cause a denial of service. It was discovered that Redis incorrectly handled certain specially crafted Lua scripts. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that Redis incorrectly handled some malformed ACL selectors. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 24.10 and Ubuntu 24.04 LTS.
