http://security.gentoo.org/

Severity:	normal
Title:	jq: Buffer overflow
Date:	12/08/2016
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	Architecture(s)
app-misc/jq	< 1.5-r2	>= 1.5-r2	All supported architectures

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"
