CVE-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 •
CVE-2023-4584 – Mozilla: Memory safety bugs fixed in Firefox 117, Firefox ESR 102.15, Firefox ESR 115.2, Thunderbird 102.15, and Thunderbird 115.2

Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and Thunderbird 115.1. 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.

CVE-2023-4580 – Mozilla: Push notifications saved to disk unencrypted
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.
