Gentoo Linux Security Advisory
Title: Xfce: Multiple vulnerabilities (GLSA 200801-06)
Severity: normal
Exploitable: remote
Date: January 09, 2008
Updated: January 10, 2008
Bug(s): #201292, #201293
ID: 200801-06
Synopsis
Multiple vulnerabilities in Xfce might allow user-assisted attackers to
execute arbitrary code.
Background
Xfce is a GTK+ 2 based desktop environment that allows to run a modern
desktop environment on modest hardware.
Affected Packages
Package: xfce-base/xfce4-panel
Vulnerable: < 4.4.2
Unaffected: >= 4.4.2
Architectures: All supported architectures
Package: xfce-base/libxfcegui4
Vulnerable: < 4.4.2
Unaffected: >= 4.4.2
Architectures: All 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:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=xfce-base/xfce4-panel-4.4.2" |
All libxfcegui4 users should upgrade to the latest version:
Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=xfce-base/libxfcegui4-4.4.2" |
