Descriptions

A malicious site could spoof the contents of the print preview window if popup windows are enabled, resulting in user confusion of what site is currently loaded. This vulnerability affects Firefox < 52 and Thunderbird < 52.

Un sitio malicioso podría suplantar el contenido de la ventana de previsualización de impresión si las ventanas emergentes están habilitadas, lo que resulta en una confusión del usuario de qué sitio está cargado actualmente. La vulnerabilidad afecta a Firefox en versiones anteriores a la 52 y Thunderbird en versiones anteriores a la 52.

USN-3216-1 fixed vulnerabilities in Firefox. The update resulted in a startup crash when Firefox is used with XRDP. This update fixes the problem. Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to bypass same origin restrictions, obtain sensitive information, spoof the addressbar, spoof the print dialog, cause a denial of service via application crash or hang, or execute arbitrary code. Various other issues were also addressed.
