Mozilla developers reported memory safety bugs present in Firefox 82. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 83.

Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Una búsqueda de una sola palabra en la barra de direcciones causó que se enviara una petición mDNS en la red local buscando un nombre de host que constara de esa cadena; resultando en una filtración de información. • https://bugzilla.mozilla.org/show_bug.cgi?id=1663571 https://www.mozilla.org/security/advisories/mfsa2020-50 https://www.mozilla.org/security/advisories/mfsa2020-51 https://www.mozilla.org/security/advisories/mfsa2020-52 •

If the Remote Debugging via USB feature was enabled in Firefox for Android on an Android version prior to Android 6.0, untrusted apps could have connected to the feature and operated with the privileges of the browser to read and interact with web content. The feature was implemented as a unix domain socket, protected by the Android SELinux policy; however, SELinux was not enforced for versions prior to 6.0. This was fixed by removing the Remote Debugging via USB feature from affected devices. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. • https://bugzilla.mozilla.org/show_bug.cgi?id=1658865 https://www.mozilla.org/security/advisories/mfsa2020-50 •
