Xfce is a GTK+ 2 based desktop environment that allows to run a modern desktop environment on modest hardware.
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).
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.
There is no known workaround at this time.
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"
