Name        : glib2
Product     : Fedora 33
Version     : 2.66.6
Release     : 1.fc33
URL         : http://www.gtk.org
Summary     : A library of handy utility functions
Description :
GLib is the low-level core library that forms the basis for projects
such as GTK+ and GNOME. It provides data structure handling for C,
portability wrappers, and interfaces for such runtime functionality
as an event loop, threads, dynamic loading, and an object system.

--------------------------------------------------------------------------------
Update Information:

* Fix various instances within GLib where `g_memdup()` was vulnerable to a
silent integer truncation and heap overflow problem (discovered by   Kevin
Backhouse, work by Philip Withnall) (#2319)  * Fix some issues with handling
over-long (invalid) input when parsing for `GDate` (!1824)  * Don���t load GIO
modules or parse other GIO environment variables when `AT_SECURE`   is set (i.e.
in a setuid/setgid/setcap process). GIO has always been   documented as not
being safe to use in privileged processes, but people persist   in using it
unsafely, so these changes should harden things against potential   attacks at
least a little. Unfortunately they break a couple of projects which   were
relying on reading `DBUS_SESSION_BUS_ADDRESS`, so GIO continues to read   that
for setgid/setcap (but not setuid) processes. This loophole will be closed   in
GLib 2.70 (see issue #2316), which should give modules 6 months to change
their behaviour. (Work by Simon McVittie and Philip Withnall) (#2168, #2305)  *
Fix `g_spawn()` searching `PATH` when it wasn���t meant to (work by   Simon
McVittie and Thomas Haller) (!1913)
