Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 24.04 LTS / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8106-1 advisory.

 It was discovered that Valkey incorrectly handled errors for lua scripts. An attacker could possibly use this issue to inject arbitrary information into the response stream for other clients. (CVE-2025-67733)

 It was discovered that Valkey incorrectly handled malformed cluster bus messages. A remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service. (CVE-2026-21863)
