     Date: December 08, 2016
     Bugs: #580606
       ID: 201612-20

Synopsis
========

A buffer overflow in jq might allow remote attackers to execute
arbitrary code.

Background
==========

jq is a lightweight and flexible command-line JSON processor.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-misc/jq                  < 1.5-r2                  >= 1.5-r2

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

An off-by-one error was discovered in the tokenadd function in
jv_parse.c which triggers a heap-based buffer overflow.

Impact
======

A remote attacker could trick a victim into processing a specially
crafted JSON file, possibly resulting in the execution of arbitrary
code with the privileges of the process.  Additionally, a remote
attacker could cause a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All jq users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-misc/jq-1.5-r2"
