CVE-2019-11757: Use-after-free when creating index updates in IndexedDB

Impact
    high

Description

When following the value's prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference it. This resulted in a use-after-free and a potentially exploitable crash.


CVE-2019-11759: Stack buffer overflow in HKDF output

Impact
    moderate

Description

An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash.


CVE-2019-11760: Stack buffer overflow in WebRTC networking

Impact
    moderate

Description

A fixed-size stack buffer could overflow in nrappkit when doing WebRTC signaling. This resulted in a potentially exploitable crash in some instances.


CVE-2019-11761: Unintended access to a privileged JSONView object

Impact
    moderate

Description

By using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms.


CVE-2019-11762: document.domain-based origin isolation has same-origin-property violation

Impact
    moderate

Description

If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window.


CVE-2019-11763: Incorrect HTML parsing results in XSS bypass technique

Impact
    moderate

Description

Failure to correctly handle null bytes when processing HTML entities resulted in Firefox incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have also led to HTML entities being masked from filters - enabling the use of entities to mask the actual characters of interest from filters.


CVE-2019-11764: Memory safety bugs fixed in Firefox 70, Firefox ESR 68.2 and Thunderbird 68.2

Impact
    critical

Description

Mozilla developers and community members Bob Clary, Jason Kratzer, Aaron Klotz, Iain Ireland, Tyson Smith, Christian Holler, Steve Fink, Honza Bambas, Byron Campen, and Cristian Brindusan reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code.
