mpv through 0.28.0 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.

The remote host is affected by the vulnerability described in GLSA-201805-05 (mpv: Remote code execution)

    A vulnerability was discovered in mpv with the handling of HTML       documents containing VIDEO elements. Additionally, mpv accepts arbitrary       URLs in a src attribute without a protocol whitelist in       player/lua/ytdl_hook.lua.
  Impact :

    A remote attacker, by enticing the user to visit a specially crafted web       site, could execute arbitrary code.
  Workaround :

    There is no known workaround at this time.

This update for mpv fixes the following issues :

MPV was updated to version 0.27.2

Security issues fixed :

  - CVE-2018-6360: Additional fix for where mpv allowed     remote attackers to execute arbitrary code via a crafted     website, because it read 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. (boo#1077894)

Fixes and minor enhancements :

  - ytdl_hook: whitelist subtitle URLs as well (#5456)

mpv developers report :

mpv through 0.28.0 allows remote attackers to execute arbitrary code via a crafted website, 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.

It was discovered that mpv, a media player, was vulnerable to remote code execution attacks. An attacker could craft a malicious web page that, when used as an argument in mpv, could execute arbitrary code in the host of the mpv user.
