Arch Linux Security Advisory ASA-201802-7 ========================================= Severity: High Date : 2018-02-13 CVE-ID : CVE-2018-6360 Package : mpv Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-605 Summary ======= The package mpv before version 1:0.27.1-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 1:0.27.1-1. # pacman -Syu "mpv>=1:0.27.1-1" The problem has been fixed upstream in version 0.27.1. Workaround ========== None. Description =========== mpv allows remote attackers to execute arbitrary code via a crafted web site, because it reads HTML documents containing VIDEO elements, and accepts arbitrary URLs in a src attribute without a protocol whitelist in player/lua/ytdl_hook.lua. For example, an av://lavfi:ladspa=file= URL signifies that the product should call dlopen on a shared object file located at an arbitrary local pathname. The issue exists because the product does not consider that youtube-dl can provide a potentially unsafe URL. Impact ====== A remote attacker can execute arbitrary code on the affected host by tricking the user into playing a malicious web page.
