Sebastian Krahmer discovered a race condition in the KDE Display Manager (KDM). A local attacker could exploit this to change the permissions on arbitrary files, thus allowing privilege escalation.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
