Discussion

KDE KDM Insecure File Permission Local Privilege Escalation Vulnerability

KDE (K Desktop Environment) KDM (KDE Display Manager) is prone to a local privilege-escalation vulnerability that stems from a race-condition error. This vulnerability occurs because the software allows attackers to modify file permissions on the computer to world-writeable.

An attacker may exploit this issue to execute arbitrary code and gain elevated privileges.

KDM packages shipped with KDE SC 2.2.0 up to and including KDE SC 4.4.2 are affected.
