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"
