GLSA-200801-06 : Xfce: Multiple vulnerabilities

Critical Nessus Plugin ID 29910


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200801-06 (Xfce: Multiple vulnerabilities)

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.


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'
