Arch Linux Security Advisory ASA-201902-19
=========================================
Severity: Critical
Date    : 2019-02-17
CVE-ID  : CVE-2018-19876
Package : cairo
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-826

Summary
======
The package cairo before version 1.16.0-2 is vulnerable to arbitrary
code execution.

Resolution
=========
Upgrade to 1.16.0-2.

# pacman -Syu "cairo>=1.16.0-2"

The problem has been fixed upstream but no release is available yet.

Workaround
=========
None.

Description
==========
A memory-corruption issue has been found in cairo versions <= 1.16.0,
in the cairo_ft_apply_variations() function in cairo-ft-font.c. This
function frees memory using the wrong free function, leading to memory
corruption. As cairo is used, among others, by WebKitGTK+, this could
be triggered by a crafted web content in some cases.

Impact
=====
A malicious remote user could execute arbitrary code by sending
specially crafted web content.
