Arch Linux Security Advisory ASA-201703-9
=========================================

Severity: High
Date    : 2017-03-14
CVE-ID  : CVE-2016-8886 CVE-2016-9591
Package : jasper
Type    : multiple issues
Remote  : Yes
Link    : https://security.archlinux.org/AVG-69

Summary
=======

The package jasper before version 2.0.12-1 is vulnerable to multiple
issues including arbitrary code execution and denial of service.

Resolution
==========

Upgrade to 2.0.12-1.

# pacman -Syu "jasper>=2.0.12-1"

The problems have been fixed upstream in version 2.0.12.

Workaround
==========

None.

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

- CVE-2016-8886 (denial of service)

A memory allocation failure was found in jas_malloc triggered by a
crafted file that results in an application crash leading to denial of
service.

- CVE-2016-9591 (arbitrary code execution)

A heap-use-after-free vulnerability has been found in jasper. The
vulnerability exists in code responsible for re-encoding the decoded
input image file to a J2P image. The vulnerability is caused by not
setting related pointers to be null after the pointers are freed (i.e.
missing Setting-Pointer-Null operations after free). The vulnerability
can further cause double-free.

Impact
======

A remote attacker is able to use specially crafted images that, when
processed, lead to arbitrary code execution or application crash.
