Title: KDE kdesu Insecure Temporary File Creation Vulnerability
Severity: MODERATE
Description:
KDESu is a frontend for su(1) used by many KDE programs for the execution of commands with elevated privileges. It is included by default with KDE's libraries.
The kdesu program creates a world-readable temporary file when exchanging authentication information. This file contains sensitive authorization information used by xauth(1) to add an authorization entry for process owner's display.
By predicting when such a temporary file will be created and the name of a file, a local attacker could use the authorization information to gain access to the X server and compromise the account accessed by kdesu.
With access to the X server, an attacker may be able to monitor keystrokes or watch X applications.
