Arch Linux Security Advisory ASA-202105-28
==========================================

Severity: Low
Date    : 2021-05-25
CVE-ID  : CVE-2021-3504
Package : hivex
Type    : denial of service
Remote  : No
Link    : https://security.archlinux.org/AVG-1907

Summary
=======

The package hivex before version 1.3.20-1 is vulnerable to denial of
service.

Resolution
==========

Upgrade to 1.3.20-1.

# pacman -Syu "hivex>=1.3.20-1"

The problem has been fixed upstream in version 1.3.20.

Workaround
==========

None.

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

A security issue was found in the hivex library before version 1.3.20.
It is caused due to a lack of bounds check within the hivex_open
function. An attacker could input a specially crafted Windows Registry
(hive) file which would cause hivex to read memory beyond its normal
bounds or cause the program to crash.

Impact
======

A crafted Windows Registry (hive) file could lead to an application
crash.
