DESCRIPTION:
A security issue has been reported in GNOME Shell, which can be
exploited by malicious, local users to gain escalated privileges.

The security issue is caused due to the gnome-shell script
incorrectly setting the environment variable LD_LIBRARY_PATH. This
can be exploited to gain escalated privileges e.g. by tricking a user
into running the script in a directory containing a malicious library.

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
