https://notcve.org/view.php?id=CVE-2023-4056
Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. 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 Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. Fallos de seguridad de memoria presentes en Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0 y Thunderbird 102.13. Algunos de estos fallos mostraban evidencias de corrupción de memoria y suponemos que con el suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1820587%2C1824634%2C1839235%2C1842325%2C1843847 https://lists.debian.org/debian-lts-announce/2023/08/msg00008.html https://lists.debian.org/debian-lts-announce/2023/08/msg00010.html https://www.debian.org/security/2023/dsa-5464 https://www.debian.org/security/2023/dsa-5469 https://www.mozilla.org/security/advisories/mfsa2023-29 https://www.mozilla.org/security/advisories/mfsa2023-30 https://www.mozilla.org/security/advisories/mfsa2023-31 https& • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2023-4055 – Mozilla: Cookie jar overflow caused unexpected cookie jar state
https://notcve.org/view.php?id=CVE-2023-4055
When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the host was no longer consistent with expected cookie jar state. This could have caused requests to be sent with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. Cuando se superaba el número de cookies por dominio en `document.cookie`, el tarro de cookies real enviado al host ya no era coherente con el estado de tarro de cookies esperado. Esto podía provocar que se enviasen peticiones en las que faltasen algunas cookies. • https://bugzilla.mozilla.org/show_bug.cgi?id=1782561 https://lists.debian.org/debian-lts-announce/2023/08/msg00008.html https://lists.debian.org/debian-lts-announce/2023/08/msg00010.html https://www.debian.org/security/2023/dsa-5464 https://www.debian.org/security/2023/dsa-5469 https://www.mozilla.org/security/advisories/mfsa2023-29 https://www.mozilla.org/security/advisories/mfsa2023-30 https://www.mozilla.org/security/advisories/mfsa2023-31 https://access.redhat.com/security • CWE-784: Reliance on Cookies without Validation and Integrity Checking in a Security Decision •

https://notcve.org/view.php?id=CVE-2023-4052
The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. • https://bugzilla.mozilla.org/show_bug.cgi?id=1824420 https://www.mozilla.org/security/advisories/mfsa2023-29 https://www.mozilla.org/security/advisories/mfsa2023-31 https://www.mozilla.org/security/advisories/mfsa2023-33 • CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2023-4050
In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This resulted in a potentially exploitable crash which could have led to a sandbox escape. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1. The Mozilla Foundation Security Advisory describes this flaw as: In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This resulted in a potentially exploitable crash which could have led to a sandbox escape. • https://bugzilla.mozilla.org/show_bug.cgi?id=1843038 https://lists.debian.org/debian-lts-announce/2023/08/msg00008.html https://lists.debian.org/debian-lts-announce/2023/08/msg00010.html https://www.debian.org/security/2023/dsa-5464 https://www.debian.org/security/2023/dsa-5469 https://www.mozilla.org/security/advisories/mfsa2023-29 https://www.mozilla.org/security/advisories/mfsa2023-30 https://www.mozilla.org/security/advisories/mfsa2023-31 https://access.redhat.com/security • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
