<title>Portage: Untrusted search path local root vulnerability</title>
|
|
<synopsis>
|
|
A search path vulnerability in Portage allows local attackers to execute
|
|
commands with root privileges if emerge is called from untrusted
|
|
directories.

Portage is Gentoo's package manager which is responsible for
|
|
installing, compiling and updating all packages on the system through
|
|
the Gentoo rsync tree.

|
The Gentoo Security Team discovered that several ebuilds, such as
|
|
sys-apps/portage, net-mail/fetchmail or app-editors/leo execute Python
|
|
code using "python -c", which includes the current working directory in
|
|
Python's module search path. For several ebuild functions, Portage did
|
|
not change the working directory from emerge's working directory.
|
|

<impact type="high">
|
|
<p>
|
|
A local attacker could place a specially crafted Python module in a
|
|
directory (such as /tmp) and entice the root user to run commands such
|
|
as "emerge sys-apps/portage" from that directory, resulting in the
|
|
execution of arbitrary Python code with root privileges.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not run "emerge" from untrusted working directories.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Portage users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# cd /root
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/portage-2.1.4.5"</code>
|
|
<p>
|
|
NOTE: To upgrade to Portage 2.1.4.5 using 2.1.4.4 or prior, you must
|
|
run emerge from a trusted working directory, such as "/root".
|
