https://notcve.org/view.php?id=CVE-2019-11761
23 Oct 2019 — 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. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Mediante el uso de un formulario con un URI de datos, fue posible conseguir acceso al objeto JSONView privilegiado que había sido clonado en contenido.

https://notcve.org/view.php?id=CVE-2019-11759
23 Oct 2019 — 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. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.

https://notcve.org/view.php?id=CVE-2019-11762
23 Oct 2019 — 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. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.

CVE-2019-11736
https://notcve.org/view.php?id=CVE-2019-11736
27 Sep 2019 — The Mozilla Maintenance Service does not guard against files being hardlinked to another file in the updates directory, allowing for the replacement of local files, including the Maintenance Service executable, which is run with privileged access. Additionally, there was a race condition during checks for junctions and symbolic links by the Maintenance Service, allowing for potential local file and directory manipulation to be undetected in some circumstances. This allows for potential privilege escalation ... • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2019-11753
https://notcve.org/view.php?id=CVE-2019-11753
27 Sep 2019 — The Firefox installer allows Firefox to be installed to a custom user writable location, leaving it unprotected from manipulation by unprivileged users or malware. If the Mozilla Maintenance Service is manipulated to update this unprotected location and the updated maintenance service in the unprotected location has been altered, the altered maintenance service can run with elevated privileges during the update process due to a lack of integrity checks. This allows for privilege escalation if the executable... • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html • CWE-354: Improper Validation of Integrity Check Value •

https://notcve.org/view.php?id=CVE-2019-9812
04 Sep 2019 — Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered.
