CVE-2020-15999 (Please update to 86.0.4240.111 ASAP)

Postby DvL » Wed Oct 21, 2020 3:40 pm

Hi,

There is a hurry behind updating the available CEF build to Chromium 86.0.4240.111, due to this incident: https://www.zdnet.com/article/google-releases-chrome-security-update-to-patch-actively-exploited-zero-day/
Hackers in question are targetting app (as in: software application) users as well.

So please, if it's possible to update faster than the usual 6-10 days you take at average to update to a new version of Chromium, do so, @magreenblatt
Thanks for considering :)

Alright, thank you very much!

I would personally advise all developers using CEF to upgrade after tomorrow.. even if your users can only browse to limited content/domains (due to the nature of your app), remotely served fonts could be fitted with the exploit.
Imagine a popular fonts CDN gets compromised, all internet users on this version of Chromium would be at huge risk during routine tasks.

For whoever build CEF themselves and emergency patching, the patch is here.
What needs to be patched is src/third_party/freetype/src/src/sfnt/pngshim.c.

Multiple platforms have built (CEF 86.0.18+gd3ead8b+chromium-86.0.4240.111), but not Windows.
If possible, make the updated Windows build available as fast as the other platforms..

The Windows builds are available (they've been available for at least 13 hours).

The http://opensource.spotify.com/cefbuilds/index.html page is cached and can take some time to update.

Can the emergency patch be applied to 4147 branch?

Probably, but you will need to build it yourself.

Yes, I did that. As stated, you need to build CEF yourself.
