GLSA-200801-06 : Xfce: Multiple vulnerabilities

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

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.

Solution :

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'

Risk factor :

Critical / CVSS Base Score : 10.0
