CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-4578 – Mozilla: Error reporting methods in SpiderMonkey could have triggered an Out of Memory Exception
https://notcve.org/view.php?id=CVE-2023-4578
When calling `JS::CheckRegExpSyntax` a Syntax Error could have been set which would end in calling `convertToRuntimeErrorAndClear`. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. Al llamar a `JS::CheckRegExpSyntax`, se podría haber establecido un error de sintaxis que terminaría llamando a `convertToRuntimeErrorAndClear`. Una ruta en la función podría intentar asignar memoria cuando no hay ninguna disponible, lo que habría provocado que una excepción de Falta de Memoria recién creada se manejara incorrectamente como un Error de Sintaxis. • https://bugzilla.mozilla.org/show_bug.cgi?id=1839007 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-2023-4578 https://bugzilla.redhat.com/show_bug.cgi?id=2236077 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2023-4580
Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. Las notificaciones push almacenadas en el disco en modo de navegación privada no estaban cifradas, lo que potencialmente permitía la filtración de información confidencial. Esta vulnerabilidad afecta a Firefox < 117, Firefox ESR < 115.2 y Thunderbird < 115.2. The Mozilla Foundation Security Advisory describes this flaw as: Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information. • https://bugzilla.mozilla.org/show_bug.cgi?id=1843046 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-2023-4580 https://bugzilla.redhat.com/show_bug.cgi?id=2236079 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-311: Missing Encryption of Sensitive Data •
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.

Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension.
