TITLE:
GNOME GLib "set_unix_mode()" Symlink Copy Insecure Permissions

SECUNIA ADVISORY ID:
SA36958

VERIFY ADVISORY:
http://secunia.com/advisories/36958/

DESCRIPTION:
A security issue has been reported in GNOME GLib, which can be
exploited by malicious, local users to disclose potentially sensitive
information and manipulate certain data.

The security issue is caused due to an error in the "set_unix_mode()"
function when setting file permissions. This can be exploited to gain
read and write access to normally restricted files or directories.

Successful exploitation requires that symlinks to protected files or
directories are copied with an application using GLib (e.g.
Nautilus).

SOLUTION:
Update to version 2.22.1.

PROVIDED AND/OR DISCOVERED BY:
Reported in an Ubuntu bug report.

ORIGINAL ADVISORY:
https://bugs.launchpad.net/ubuntu/+source/glib2.0/+bug/418135
https://bugzilla.gnome.org/show_bug.cgi?id=593406
