https://notcve.org/view.php?id=CVE-2022-1196
After a VR Process is destroyed, a reference to it may have been retained and used, leading to a use-after-free and potentially exploitable crash. This vulnerability affects Thunderbird < 91.8 and Firefox ESR < 91.8. Después de que se destruye un proceso de realidad virtual, es posible que se haya conservado y utilizado una referencia al mismo, lo que ha provocado un bloqueo de un use-after-free y potencialmente explotable. Esta vulnerabilidad afecta a Thunderbird < 91.8 y Firefox ESR < 91.8. A flaw was found in Mozilla. • https://bugzilla.mozilla.org/show_bug.cgi?id=1750679 https://www.mozilla.org/security/advisories/mfsa2022-14 https://www.mozilla.org/security/advisories/mfsa2022-15 https://access.redhat.com/security/cve/CVE-2022-1196 https://bugzilla.redhat.com/show_bug.cgi?id=2072561 • CWE-416: Use After Free •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 4CVE-2022-28285 – Mozilla: Incorrect AliasSet used in JIT Codegen
https://notcve.org/view.php?id=CVE-2022-28285
When generating the assembly code for <code>MLoadTypedArrayElementHole</code>, an incorrect AliasSet was used. In conjunction with another vulnerability this could have been used for an out of bounds memory read. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. Al generar el código ensamblador para <code>MLoadTypedArrayElementHole</code>, se utilizó un AliasSet incorrecto. Junto con otra vulnerabilidad, esto podría haberse utilizado para una lectura de memoria fuera de los límites. • https://bugzilla.mozilla.org/show_bug.cgi?id=1756957 https://www.mozilla.org/security/advisories/mfsa2022-13 https://www.mozilla.org/security/advisories/mfsa2022-14 https://www.mozilla.org/security/advisories/mfsa2022-15 https://access.redhat.com/security/cve/CVE-2022-28285 https://bugzilla.redhat.com/show_bug.cgi?id=2072563 • CWE-125: Out-of-bounds Read •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 5CVE-2022-28281 – Mozilla: Out of bounds write due to unexpected WebAuthN Extensions
https://notcve.org/view.php?id=CVE-2022-28281
If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to the parent process, an out of bounds write would have occurred leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. Si un proceso de contenido comprometido envió una cantidad inesperada de extensiones WebAuthN en un comando de registro al proceso principal, se habría producido una escritura fuera de los límites que provocaría daños en la memoria y un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Thunderbird < 91.8, Firefox < 99 y Firefox ESR < 91.8. The Mozilla Foundation Security Advisory describes this flaw as: If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to the parent process, an out of bounds write would have occurred leading to memory corruption and a potentially exploitable crash. • https://github.com/0vercl0k/CVE-2022-28281 https://bugzilla.mozilla.org/show_bug.cgi?id=1755621 https://www.mozilla.org/security/advisories/mfsa2022-13 https://www.mozilla.org/security/advisories/mfsa2022-14 https://www.mozilla.org/security/advisories/mfsa2022-15 https://access.redhat.com/security/cve/CVE-2022-28281 https://bugzilla.redhat.com/show_bug.cgi?id=2072560 • CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-28289 – Mozilla: Memory safety bugs fixed in Firefox 99 and Firefox ESR 91.8
https://notcve.org/view.php?id=CVE-2022-28289
Mozilla developers and community members Nika Layzell, Andrew McCreight, Gabriele Svelto, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 91.7. 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 Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. Los desarrolladores de Mozilla y miembros de la comunidad Nika Layzell, Andrew McCreight, Gabriele Svelto y el equipo Mozilla Fuzzing informaron sobre errores de seguridad de la memoria presentes en Thunderbird 91.7. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haberse aprovechado para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1663508%2C1744525%2C1753508%2C1757476%2C1757805%2C1758549%2C1758776 https://www.mozilla.org/security/advisories/mfsa2022-13 https://www.mozilla.org/security/advisories/mfsa2022-14 https://www.mozilla.org/security/advisories/mfsa2022-15 https://access.redhat.com/security/cve/CVE-2022-28289 https://bugzilla.redhat.com/show_bug.cgi?id=2072566 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
