Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D
Multiple integer overflows might allow for the execution of arbitrary
code when performing base64 conversion.
Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
The GLib is a library of C routines that is used by a multitude of
programs.
Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/glib < 2.18.4-r1 >=3D 2.18.4-r1
*>=3D 2.16.6-r1
Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Diego E. Petten=F2 reported multiple integer overflows in glib/gbase64.c
when converting a long string from or to a base64 representation.
Impact
=3D=3D=3D=3D=3D=3D
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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
There is no known workaround at this time.
Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
All GLib 2.18 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Ddev-libs/glib-2.18.4-r1"
All GLib 2.16 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=3Ddev-libs/glib-2.16.6-r1"
