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 >=3D 2.18.4-r1 *>=3D 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 ">=3Ddev-libs/glib-2.18.4-r1"
All GLib 2.16 users should upgrade to the latest version:
