Update Firefox again – more RCEs and an Android “takeover” bug too
2020-04-08 11:17

We'll refer to this one a Fourthytuesday instead, now that Firefox has reduced its update wavelength to four weeks to get important-but-not-zero-day-critical fixes out just that bit more frequently.

If your automatic update hasn't happened yet, a manual check will let you "Jump the queue" and get the update a bit sooner.

CVE-2020-6828: Preference overwrite via crafted Intent from malicious Android application A malicious Android application could craft an Intent that would have been processed by Firefox for Android and potentially result in a file overwrite in the user's profile directory.

CVE-2020-6824: Generated passwords may be identical on the same site between separate private browsing sessions Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open.

Going to a website to change your password - after a breach notification, for example - is likely enough, but changing it twice in a row to a "Random" password without exiting Firefox inbetween isn't likely at all.
