SB2025123064 - openEuler 24.03 LTS SP2 update for redis6

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Resource management error (CVE-ID: CVE-2025-21605)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application when handling output buffers. A remote attacker can cause the output buffer to grow from "NOAUTH" responses until the system will run out of memory.

2) Out-of-bounds write (CVE-ID: CVE-2025-32023)

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to a boundary error on hyperloglog operations. A remote user can trigger an out-of-bounds write and execute arbitrary code on the target system.

3) Integer overflow (CVE-ID: CVE-2025-46817)

The vulnerability allows a remote user to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow when processing Lua scripts. A remote user can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

4) Improper authentication (CVE-ID: CVE-2025-46818)

The vulnerability allows a remote user to escalate privileges within the application.

The vulnerability exists due to an error when handling Lua scripts. A remote user can manipulate different LUA objects and potentially run their own code in the context of another user.

5) Out-of-bounds read (CVE-ID: CVE-2025-46819)

The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when processing Lua scripts. A remote user  can trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.

6) Resource management error (CVE-ID: CVE-2025-48367)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources within the application when handling connection errors. A remote non-authenticated attacker can cause repeated IP protocol errors leading to client starvation and a denial of service condition.
