Descriptions

The file picker dialog can choose and display the wrong local default directory when instantiated. On some operating systems, this can lead to information disclosure, such as the operating system or the local account name. This vulnerability affects Firefox < 52 and Thunderbird < 52.

El diálogo file picker puede elegir y mostrar el directorio local por defecto equivocado cuando se instancia. En algunos sistemas operativos, esto puede conducir a una divulgación de información, como el sistema operativo o el nombre de la cuenta local. 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.
