https://notcve.org/view.php?id=CVE-2022-31736
A malicious website could have learned the size of a cross-origin resource that supported Range requests. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. Un sitio web malicioso podría haber aprendido el tamaño de un recurso de origen cruzado que admitiera solicitudes de rango. Esta vulnerabilidad afecta a Thunderbird < 91.10, Firefox < 101 y Firefox ESR < 91.10. The Mozilla Foundation Security Advisory describes this flaw as: A malicious website that could have learned the size of a cross-origin resource that supported Range requests. • https://bugzilla.mozilla.org/show_bug.cgi?id=1735923 https://www.mozilla.org/security/advisories/mfsa2022-20 https://www.mozilla.org/security/advisories/mfsa2022-21 https://www.mozilla.org/security/advisories/mfsa2022-22 https://access.redhat.com/security/cve/CVE-2022-31736 https://bugzilla.redhat.com/show_bug.cgi?id=2092018 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-31742 – Mozilla: Querying a WebAuthn token with a large number of allowCredential entries may have leaked cross-origin information
https://notcve.org/view.php?id=CVE-2022-31742
An attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have led to cross-origin account linking in violation of WebAuthn goals. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. Un atacante podría haber aprovechado un ataque de sincronización enviando una gran cantidad de entradas allowCredential y detectando la diferencia entre identificadores de claves no válidas y identificadores de claves de origen cruzado. Esto podría haber llevado a la vinculación de cuentas entre orígenes en violación de los objetivos de WebAuthn. • https://bugzilla.mozilla.org/show_bug.cgi?id=1730434 https://www.mozilla.org/security/advisories/mfsa2022-20 https://www.mozilla.org/security/advisories/mfsa2022-21 https://www.mozilla.org/security/advisories/mfsa2022-22 https://access.redhat.com/security/cve/CVE-2022-31742 https://bugzilla.redhat.com/show_bug.cgi?id=2092025 • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

https://notcve.org/view.php?id=CVE-2022-1802
If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution, they could have achieved execution of attacker-controlled JavaScript code in a privileged context. This vulnerability affects Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox for Android < 100.3.0, and Thunderbird < 91.9.1. Si un atacante pudo corromper los métodos de un objeto Array en JavaScript mediante la contaminación de prototipos, podría haber logrado la ejecución del código JavaScript controlado por el atacante en un contexto privilegiado. Esta vulnerabilidad afecta a Firefox ESR < 91.9.1, Firefox < 100.0.2, Firefox para Android < 100.3.0 y Thunderbird < 91.9.1.
