CVE-2024-52336

Tuned is a daemon that uses udev to monitor connected devices and statically and dynamically tunes system settings according to a selected profile. It is distributed with a number of predefined profiles for common use cases like high throughput, low latency, or powersave, and allows you to further alter the rules defined for each profile and customize how to tune a particular device. To revert all changes made to the system settings by a certain profile, you can either switch to another profile or deactivate the tuned daemon.

Security Fix(es):

A script injection vulnerability was identified in the Tuned package. The instance_create() D-Bus function can be called by locally logged-in users without authentication. This flaw allows a local non-privileged user to execute a D-Bus call with script_pre or script_post options that permit arbitrary scripts with their absolute paths to be passed. These user or attacker-controlled executable scripts or programs could then be executed by Tuned with root privileges that could allow attackers to local privilege escalation.(CVE-2024-52336)

A log spoofing flaw was found in the Tuned package due to improper sanitization of some API arguments. This flaw allows an attacker to pass a controlled sequence of characters; newlines can be inserted into the log. Instead of the 'evil' the attacker could mimic a valid TuneD log line and trick the administrator. The quotes '' are usually used in TuneD logs citing raw user input, so there will always be the ' character ending the spoofed input, and the administrator can easily overlook this. This logged string is later used in logging and in the output of utilities, for example, tuned-adm get_instances or other third-party programs that use Tuned's D-Bus interface for such operations.(CVE-2024-52337)

The tuned packages provide a service that tunes system settings according to a selected profile.

Security Fix(es):

• tuned: script_pre and script_post options allow to pass arbitrary scripts executed by root (CVE-2024-52336)
• tuned: improper sanitization of instance_name parameter of the instance_create() method (CVE-2024-52337)
