Synopsis
========
gtkdiskfree is vulnerable to symlink attacks, potentially allowing a
local user to overwrite arbitrary files.
Background
==========
gtkdiskfree is a GTK-based GUI to show free disk space.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/gtkdiskfree lt; 1.9.3-r1 gt;= 1.9.3-r1
Description
===========
Eric Romang discovered that gtkdiskfree insecurely creates a
predictable temporary file to handle command output.
Impact
======
A local attacker could create a symbolic link in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
gtkdiskfree is executed, this would result in the file being
overwritten with the rights of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All gtkdiskfree users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=app-admin/gtkdiskfree-1.9.3-r1"
