[Remi Gacogne]

Arch Linux Security Advisory ASA-201708-12
==========================================

Severity: High
Date    : 2017-08-14
CVE-ID  : CVE-2017-7506
Package : spice
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-349

Summary
=======

The package spice before version 0.12.8+8+ga957a90b-1 is vulnerable to
arbitrary code execution.

Resolution
==========

Upgrade to 0.12.8+8+ga957a90b-1.

# pacman -Syu "spice>=0.12.8+8+ga957a90b-1"

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

Workaround
==========

None.

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

Two security issues have been found in spice <= 0.12.8, allowing a
remote, authenticated user to get access to memory content by sending a
number of monitors bigger than the number of items, and to trigger an
integer overflow of the buffer_size variable, leading to a potentially
exploitable buffer overflow.

Impact
======

A remote, authenticated attacker can access sensitive information or
execute arbitrary code on the affected host.
