Background ========== Xfce is a GTK+ 2 based desktop environment that allows to run a modern desktop environment on modest hardware. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 xfce-base/xfce4-panel < 4.4.2 >= 4.4.2 2 xfce-base/libxfcegui4 < 4.4.2 >= 4.4.2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Gregory Andersen reported that the Xfce4 panel does not correctly calculate memory boundaries, leading to a stack-based buffer overflow in the launcher_update_panel_entry() function (CVE-2007-6531). Daichi Kawahata reported libxfcegui4 did not copy provided values when creating "SessionClient" structs, possibly leading to access of freed memory areas (CVE-2007-6532). Impact ====== A remote attacker could entice a user to install a specially crafted "rc" file to execute arbitrary code via long strings in the "Name" and "Comment" fields or via unspecified vectors involving the second vulnerability. Workaround ========== There is no known workaround at this time. Resolution ========== All Xfce4 panel users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=xfce-base/xfce4-panel-4.4.2" All libxfcegui4 users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=xfce-base/libxfcegui4-4.4.2" Please refer to the Upgrading section of the Xfce Configuration Guide in case you are upgrading from Xfce 4.2.
