Description:
Three vulnerabilities have been reported in GNOME Display Manager (GDM), which can be exploited by malicious users to read arbitrary files on the system or cause a Denial of Service (DoS).
The first vulnerability is caused due to an error in the "examine session errors" feature. The problem is that GDM reads the "~/.xsession-errors" file with "root" privileges, which can be exploited to disclose the content of arbitrary files on the system via a symlink attack.
Successful exploitation requires that the session lasts less than 10 seconds.
The two other vulnerabilities are caused due to errors in the X Display Manager Control Protocol (XDMCP), which can be exploited by malicious people to crash the gdm daemon.
