Arch Linux Security Advisory ASA-201903-10
==========================================

Severity: High
Date    : 2019-03-18
CVE-ID  : CVE-2019-8943
Package : wordpress
Type    : directory traversal
Remote  : Yes
Link    : https://security.archlinux.org/AVG-909

Summary
=======

The package wordpress before version 5.1-1 is vulnerable to directory
traversal.

Resolution
==========

Upgrade to 5.1-1.

# pacman -Syu "wordpress>=5.1-1"

The problem has been fixed upstream in version 5.1.

Workaround
==========

None.

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

WordPress through 5.0.3 allows Path Traversal in wp_crop_image(). An
attacker (who has privileges to crop an image) can write the output
image to an arbitrary directory via a filename containing two image
extensions and ../ sequences, such as a filename ending with the
.jpg?/../../file.jpg substring.

Impact
======

A remote attacker with image-cropping privileges can write files to an
arbitrary directory
