Descriptions

A phishing site could have repurposed an `about:` dialog to show phishing content with an incorrect origin in the address bar. This vulnerability affects Firefox < 122 and Thunderbird < 115.7.

Un sitio de phishing podría haber reutilizado un cuadro de diálogo "acerca de:" para mostrar contenido de phishing con un origen incorrecto en la barra de direcciones. Esta vulnerabilidad afecta a Firefox < 122, Firefox ESR < 115.7 y Thunderbird < 115.7.

The Mozilla Foundation Security Advisory describes this flaw as: A phishing site could have repurposed an `about:` dialog to show phishing content with an incorrect origin in the address bar.

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Cornel Ionce discovered that Firefox did not properly manage memory when opening the print preview dialog. An attacker could potentially exploit this issue to cause a denial of service.
