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: dev-libs/glib
Vulnerable: < 2.18.4-r1
Unaffected: >= 2.18.4-r1

Description

Diego E. Petteno` 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:
