On Windows, an integer overflow could occur in `RecordedSourceSurfaceCreation` which resulted in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. En Windows, podría ocurrir un desbordamiento de enteros en `RecordedSourceSurfaceCreation`, lo que resultó en un desbordamiento del búfer que podría filtrar datos confidenciales que podrían haber llevado a un escape de la sandbox. *Este error sólo afecta a Firefox en Windows. Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2 y Thunderbird < 115.2. • https://bugzilla.mozilla.org/show_bug.cgi?id=1846694 https://www.mozilla.org/security/advisories/mfsa2023-34 https://www.mozilla.org/security/advisories/mfsa2023-35 https://www.mozilla.org/security/advisories/mfsa2023-36 https://www.mozilla.org/security/advisories/mfsa2023-37 https://www.mozilla.org/security/advisories/mfsa2023-38 • CWE-190: Integer Overflow or Wraparound •

Excel `.xll` add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed them to be downloaded without any warning of their potential harm. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. Los archivos complementarios `.xll` de Excel no tenían una entrada en la lista de bloqueo ejecutable de Firefox, lo que permitía descargarlos sin ninguna advertencia sobre su daño potencial. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2 y Thunderbird < 115.2.

CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-4583 – Mozilla: Browsing Context potentially not cleared when closing Private Window
https://notcve.org/view.php?id=CVE-2023-4583
When checking if the Browsing Context had been discarded in `HttpBaseChannel`, if the load group was not available then it was assumed to have already been discarded which was not always the case for private channels after the private session had ended. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. Al comprobar si el contexto de navegación se había descartado en `HttpBaseChannel`, si el grupo de carga no estaba disponible, se suponía que ya se había descartado, lo que no siempre era el caso para los canales privados después de que finalizaba la sesión privada. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 115.2 y Thunderbird < 115.2. The Mozilla Foundation Security Advisory describes this flaw as: When checking if the Browsing Context had been discarded in `HttpBaseChannel`, if the load group was not available then it was assumed to have already been discarded which was not always the case for private channels after the private session had ended. • https://bugzilla.mozilla.org/show_bug.cgi?id=1842030 https://www.mozilla.org/security/advisories/mfsa2023-34 https://www.mozilla.org/security/advisories/mfsa2023-36 https://www.mozilla.org/security/advisories/mfsa2023-38 https://access.redhat.com/security/cve/CVE-2023-4583 https://bugzilla.redhat.com/show_bug.cgi?id=2236082 • CWE-179: Incorrect Behavior Order: Early Validation CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2023-4579
Search queries in the default search engine could appear to have been the currently navigated URL if the search query itself was a well formed URL. This could have led to a site spoofing another if it had been maliciously set as the default search engine. This vulnerability affects Firefox < 117. Las consultas de búsqueda en el motor de búsqueda predeterminado podrían parecer haber sido la URL navegada actualmente si la consulta de búsqueda en sí fuera una URL bien formada. Esto podría haber llevado a que un sitio suplantara a otro si se hubiera configurado maliciosamente como motor de búsqueda predeterminado. • https://bugzilla.mozilla.org/show_bug.cgi?id=1842766 https://security.gentoo.org/glsa/202401-10 https://www.mozilla.org/security/advisories/mfsa2023-34 •
