Multiple vulnerabilities have been identified in Xfce, which could be exploited to cause a denial of service or execute arbitrary code. These issues are caused by buffer overflow errors in the "libxfce4panel/xfce-panel-plugin-iface.c", "panel/panel-dialogs.c", "panel/panel.c" "plugins/clock/clock.c" "plugins/launcher/launcher-dialog.c" and "plugins/launcher/launcher.c" files when handling and passing overly long data to the "g_strlcpy()" and "g_snprintf()" functions, which could be exploited to crash a vulnerable application or potentially compromise an affected system.
Note: A double free error also exists in libxfcegui4 when creating "SessionClient" structs.
