The bad news is that Android is still likely affected. Similar to Apple’s ImageIO, Android has a facility called the BitmapFactory that handles image decoding, and of course libwebp is supported. As of today, Android hasn’t released a security bulletin that includes a fix for CVE-2023-4863 – although the fix has been merged into AOSP. To put this in context: if this bug does affect Android, then it could potentially be turned into a remote exploit for apps like Signal and WhatsApp. I’d expect it to be fixed in the October bulletin.
