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 https://www.cve.org/CVERecord?id=CVE-2008-4316 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200904-02 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.
