CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2020-6807 – Mozilla: Use-after-free in cubeb during stream destruction
https://notcve.org/view.php?id=CVE-2020-6807
When a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. Cuando un dispositivo fue cambiado mientras una secuencia estaba a punto de ser destruida, la tarea <code>stream-reinit</code> pudo haberse ejecutado después de que la secuencia fue destruida, causando un uso de la memoria previamente liberada y un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 68.6, Firefox versiones anteriores a 74, Firefox versiones anteriores a ESR68.6 y Firefox ESR versiones anteriores a 68.6. The Mozilla Foundation Security Advisory describes this flaw as: When a device was changed while a stream was about to be destroyed, the `stream-reinit` task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash. • https://bugzilla.mozilla.org/show_bug.cgi?id=1614971 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-08 https://www.mozilla.org/security/advisories/mfsa2020-09 https://www.mozilla.org/security/advisories/mfsa2020-10 https://access.redhat.com/security/cve/CVE-2020-6807 https://bugzilla.redhat.com/show_bug.cgi?id=1812201 • CWE-416: Use After Free •

CVSS: 8.8EPSS: 1%CPEs: 6EXPL: 1CVE-2020-6811 – Mozilla: Devtools' 'Copy as cURL' feature did not fully escape website-controlled data, potentially leading to command injection
https://notcve.org/view.php?id=CVE-2020-6811
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. La funcionalidad "Copy as cURL" de la pestaña de red de Devtools no escapó correctamente el método HTTP de una petición, que puede ser controlada por el sitio web. Si un usuario utilizó la funcionalidad "Copy as Curl" y pegó el comando a un terminal, podría haber resultado en una inyección de comandos y una ejecución de comandos arbitraria. • https://bugzilla.mozilla.org/show_bug.cgi?id=1607742 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-08 https://www.mozilla.org/security/advisories/mfsa2020-09 https://www.mozilla.org/security/advisories/mfsa2020-10 https://access.redhat.com/security/cve/CVE-2020-6811 https://bugzilla.redhat.com/show_bug.cgi?id=1812202 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 6.1EPSS: 0%CPEs: 6EXPL: 0CVE-2020-6812 – Mozilla: The names of AirPods with personally identifiable information were exposed to websites with camera or microphone permission
https://notcve.org/view.php?id=CVE-2020-6812
The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. • https://bugzilla.mozilla.org/show_bug.cgi?id=1616661 https://usn.ubuntu.com/4328-1 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2020-08 https://www.mozilla.org/security/advisories/mfsa2020-09 https://www.mozilla.org/security/advisories/mfsa2020-10 https://access.redhat.com/security/cve/CVE-2020-6812 https://bugzilla.redhat.com/show_bug.cgi?id=1812204 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
