Synopsis
=======
Multiple integer overflows might allow for the execution of arbitrary
code when performing base64 conversion.

Background
=========
The GLib is a library of C routines that is used by a multitude of
programs.

Affected packages
================
    -------------------------------------------------------------------
     Package        /   Vulnerable   /                      Unaffected
    -------------------------------------------------------------------
  1  dev-libs/glib      < 2.18.4-r1                       >= 2.18.4-r1
                                                         *>= 2.16.6-r1

Description
==========
Diego E. Petten=F2 reported multiple integer overflows in glib/gbase64.c
when converting a long string from or to a base64 representation.

Impact
=====
A remote attacker could entice a user or automated system to perform a
base64 conversion via an application using GLib, possibly resulting in
the execution of arbitrary code.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All GLib 2.18 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.18.4-r1"

All GLib 2.16 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/glib-2.16.6-r1"
