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

medium Nessus Plugin ID 34383

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-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.

Solution

All Portage users should upgrade to the latest version:
 # cd /root # emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/portage-2.1.4.5' 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'.
