Summary
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.
Risk Assessment
The risk is that an administrator may be deceived by forged log entries, which can hinder detection of actual attacks or configuration errors. Additionally, the spoofed string may be displayed in tools such as `tuned-adm get_instances` or other programs using Tuned's D-Bus interface.
Recommendation
It is recommended to immediately update the Tuned package to a version that fixes this vulnerability. Until the update is applied, restrict access to the Tuned D-Bus interface to trusted users and processes only.
Original NVD description (English source)
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.
