Summary
blueman vulnerability
Details

Vaisha Bernard discovered that blueman did not properly sanitize input on the d-bus interface to blueman-mechanism. A local attacker could possibly use this issue to escalate privileges and run arbitrary code or cause a denial of service. (CVE-2020-15238)

While a previous security update fixed the issue, this update provides additional improvements by enabling PolicyKit authentication for privileged commands.
