New description:

 As the title states, audio/video uploads are broken in the 4.2.13 and
 4.3.9 security releases.

 These releases backport a function for validating metadata,
 `wp_kses_post_deep`, but this function wasn't introduced until 4.4.

 Uploading an audio/video file will respond with an undefined function
 error.

 Relevant 4.2 commit: [40148]

 Relevant 4.3 commit: [40153]

 Trac doesn't let me choose 4.2.13, so I've filed this against trunk.

Comment:

 Hi @uzegonemad, welcome to Trac! Thanks for the report.

 I can confirm the issue. [40148] was backported to all branches from 3.7
 to 4.3, so they all appear to be affected.
