Descriptions

In certain circumstances a networking event listener can be prematurely released. This appears to result in a null dereference in practice. This vulnerability affects Firefox < 52 and Thunderbird < 52.

En determinadas circunstancias, un escuchador de eventos de red puede liberarse prematuramente. Esto parece resultar en la práctica en una desreferencia NULL. 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.
