@@ -1,62 +0,0 @@
Incorrect command-line parameter validation in the Xorg X server can lead to
privilege elevation and/or arbitrary files overwrite, when the X server is
running with elevated privileges (ie when Xorg is installed with the setuid bit
set and started by a non-root user). The -modulepath argument can be used to
specify an insecure path to modules that are going to be loaded in the X server,
allowing to execute unprivileged code in the privileged process. The -logfile
argument can be used to overwrite arbitrary files in the file system, due to
incorrect checks in the parsing of the option.
