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. 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" References ========== [ 1 ] CVE-2008-4316 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4316 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-02.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
