ArchLinux: 201902-4 Critical: Spice Arbitrary Code Execution

Arch Linux Security Advisory ASA-201902-4
========================================
Severity: Critical
Date    : 2019-02-11
CVE-ID  : CVE-2019-3813
Package : spice
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-866

Summary
======
The package spice before version 0.14.0-3 is vulnerable to arbitrary
code execution.

Resolution
=========
Upgrade to 0.14.0-3.

# pacman -Syu "spice>=0.14.0-3"

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

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

Description
==========
Spice, versions 0.5.2 through 0.14.1, are vulnerable to an out-of-bounds read due to an off-by-one error in memslot_get_virt. This may
lead to a denial of service, or, in the worst case, code-execution by
unauthenticated attackers.

Impact
=====
A remote, unauthenticated attacker might be able to crash the server,
or even execute arbitrary code on said server.
