GLSA-200810-02 : Portage: Untrusted search path local root vulnerability

Medium Nessus Plugin ID 34383


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


The remote host is affected by the vulnerability described in GLSA-200810-02 (Portage: Untrusted search path local root vulnerability)

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 :

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.
Workaround :

Do not run 'emerge' from untrusted working directories.


All Portage users should upgrade to the latest version:
# cd /root # emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/portage-' NOTE: To upgrade to Portage using or prior, you must run emerge from a trusted working directory, such as '/root'.
