Severity: Normal
Title: runC: Privilege escalation
Date: January 12, 2017
Bugs: #605378
ID: 201701-34

– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –

Synopsis
========

A vulnerability in runC could lead to privilege escalation.

Background
==========

RunC is a CLI tool for spawning and running containers according to the
OCI specification.

Affected packages
=================

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 app-emulation/runc < 1.0.0_rc2-r2 >= 1.0.0_rc2-r2

Description
===========

A vulnerability was discovered in runC that allows additional container
processes via ‘runc exec’ to be ptraced by the pid 1 of the container.
This allows the main processes of the container, if running as root, to
gain access to file-descriptors of these new processes.

Impact
======

An attacker, who is able to successfully escape the container or modify
runC’s state before process initialization, could escalate privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All runC users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot -v “>=app-emulation/runc-1.0.0_rc2-r2”
