Severity: Normal
Title: GLib: Execution of arbitrary code
Date: April 03, 2009
Bugs: #249214
ID: 200904-02
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
==========
Diego E. Pettenò 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"
